Chapter 427 Listen to Me and Try Not to Suffer!

Domestic research and development of turbine blades are all optimistic about the direction of single crystal nickel, because "single crystal" is a new technology that allows the elements and atoms that make up the alloy to maintain a unified direction to increase the performance of the alloy, which is very scientific.

The difference between single crystal nickel alloy and ordinary alloy is that the nickel content is higher.

Nickel has good plasticity and a high degree of polishing and corrosion resistance. Many alloy-related studies have shown that high nickel content can help improve high temperature resistance and strength.

In addition, an important reason for seeing the direction of single crystal nickel in China is that the world's top turbine engine blades use single crystal nickel alloys.

The road ahead has been cleared, and as long as we continue to work hard, we will definitely have results.

The direction of nickel-iron alloy is very common.

Nickel-iron alloys have not improved for many years and are still products from the past few decades.

If we distinguish between the direction of single crystal nickel and the direction of nickel-iron alloy, we can say that single crystal nickel represents the latest alloy technology and research and development direction, while nickel-iron alloy belongs to the 'traditional' technology.

Tradition seems to be eliminated.

This time Zhao Yi is in the ‘traditional’ camp. The reason is not that he is not optimistic about the direction of single crystal nickel, but...

trouble!

It is too troublesome to apply for the research and development of single crystal nickel, and it is also too troublesome to do the research and development of single crystal nickel. The latest technology also represents complexity. The process of 'single crystal' technology requires very high-end equipment, let alone starting from DD5. , we also have to deal with the Institute of Metal Research of the Academy of Sciences, and continue to do research and development with their results. Whose result will it be after success?

After careful consideration, he determined that it was enough to improve the nickel-iron alloy technology and improve the performance of the final alloy according to the existing needs, and did not require "too advanced" technology.

This is also the simplest and easiest direction.

After Zhao Yi and Zhang Hongtao agreed, they quickly expanded the names of the people involved in the research and development. Zhao Yi added Shen Binghe. Shen Binghe was also the only person Yanhua University could name who was related to alloy materials research. Zhang Hongtao added Added Wang Zhifang's name.

There are four people participating in the research, namely Zhao Yi, Shen Binghe, Zhang Hongtao and Er Wang Zhifang.

They were the ‘expert group’ who visited the 307 Steel Plant.

After the project was approved, Zhao Yi applied to visit the 307 Steel Plant to visit the manufacturing process of nickel-iron alloy turbine blades. He received the agreement and reported the list of participants.

Personnel approval is very fast, but the time arrangement still depends on the situation at the 307 Steel Plant.

…

307 steel mill.

Like other factories with code names, 307 Steel Factory also has a purely military background and is a factory that specializes in producing alloy materials for the military.

307 Steel Factory has very complete production and manufacturing equipment, and has a research and development team belonging to the steel factory. It will participate in many national-defense and military-industrial projects, including military weapons such as fighter jets, submarines, and tanks. The production process includes 307 steel. Factory shadow.

Although the 307 Steel Plant is state-owned and owned by the military, the R&D department of the steel plant is a bit embarrassing, especially the R&D groups of some high-tech materials, which are even more embarrassing to the point of "no sense of existence."

This is the case for the aviation materials R&D team.

A few decades ago, the steel, products and technologies produced by 307 Steel Plant came from the internal R&D group, which was equivalent to doing its own research and development and production. However, with the continuous advancement of science and technology, the capabilities of the aviation materials R&D group have been far beyond their capabilities. To meet the demand for materials in the aviation field, steel mills have no choice but to use the results of external scientific institutions.

This makes the existence of the aviation materials research and development group very embarrassing.

If the production of materials in the aviation field uses the research and development results and directions of external institutions, they will become meaningless. However, it is a fact that their research and development capabilities cannot keep up. They have the best scientific research conditions, but they do not have the corresponding ability to attract talents. ability.

He Guilin, the current leader of the aviation materials R&D group, has always been worried about this matter. He is worried that one day, the steel factory will cancel the aviation materials R&D group. But the problem he faces is that their aviation materials group has been there for several years. Time, no material research and development breakthroughs.

Talent is the most important thing.

He Guilin hopes that more alloy material experts can join the aerospace materials research and development team of the steel plant. However, it is a pity that most of the truly capable talents will choose to work in universities, academies of science, or corporate scientific research institutions. , and without talents, it will be more difficult for his aviation materials research and development team to produce any results.

"Alas~~"

He Guilin sat on a chair and read several reports of failed R&D experiments in succession. He was filled with helplessness and he could only sigh.

"Report!"

A shout came from the door.

"Enter!"

He Guilin shouted softly, and a staff member walked in and handed over a document, "This is the above document for you to sign."

"Let me see."

He Guilin glanced at the documents and knew that a 'group of experts' had come to visit the turbine blade material manufacturing process.

He couldn't help but the corners of his mouth twitched.

The material of turbine blades is nickel-iron alloy, and outside institutions are developing single-crystal nickel alloys. Single-crystal nickel alloys are considered to be the cutting-edge direction. This is where the embarrassment lies. No one in his aviation materials research and development team understands single-crystal technology. Researchers at the Institute of Technology are also doing research and development in the direction of single crystal nickel, but they have only made a beginning and don’t know how to continue.

"I guess they are making single crystal nickel alloy again. Let's take a look at the manufacturing process of nickel-iron alloy and give a reference for the direction of single crystal nickel."

"If this continues, the aerospace materials research and development team will be dispensable. 307 will not even have any of its own technology and will soon become a pure factory."

"Alas~"

He Guilin sighed again and signed his name on the document.

…

Institute of Metal Research, Academy of Sciences.

The Capital Institute of Aeronautical Materials was the first to study single crystal nickel alloys in China. The Institute of Metal Research of the Academy of Sciences, relying on its strong talent pool and scientific research capabilities, came from behind to develop DD5 and continues to make improvements to enhance the performance of the alloy.

The leader of this research is Academician Peng Engui. He is the leading alloy materials expert in China and has led the research and development of more than a dozen alloy materials that have caught up with the world level.

Peng Engui undoubtedly has a strong say in the materials of turbine blades, and news in the industry cannot escape his ears.

soon.

Peng Engui and the R&D team he led knew that there was a third research and development project on turbine blade materials in China, and they also knew that Zhao Yi and Zhang Hongtao jointly applied for it.

It wasn't a big deal at first. At most, there was competition in terms of research and development speed, but he also heard that Zhao Yi's application report was written in the direction of 'nickel-iron alloy', and it became very interesting.

The two research and development directions are naturally not competitors.

Peng Engui entered the laboratory and several people in the research team. It was a bit funny when he talked about it, "Zhao Yi, researching alloy materials? Did he switch from theory to application? Even if he switched to application, it should be applied mathematics. What are you doing? Alloy Materials Research.”

He shook his head as he spoke, and said in a teaching manner, "In our industry, what is the most important thing? Experience!"

“Experience is the most important thing!”

"Mathematics and physics, for example, are all based on theory. Only with the support of theory can we develop applied mathematics and applied physics. Alloy materials are different. If you talk about theory, can you deduce the manufacturing method of alloy? No!"

"This research is a process of continuous trial and error and continuous improvement. Knowledge is all in the process of experimentation and research, so experience is the most important."

Several researchers also nodded, "Academician Peng is right! It makes sense!"

"Our research is all about trial and error. Maybe by increasing the temperature and time in that step, it will work!"

"Academician Peng speaks from experience!"

Peng Engui felt a little embarrassed after being praised for a few words, so he continued, "Zhao Yi, let's not talk about geniuses. Zhang Hongtao has some abilities. He is really lucky. He can imitate the skin of a satellite at a young age. , it is said that research on aircraft carrier decks has also yielded results.”

"Shuanghang's alloy laboratory is also of high quality. Academician Wang Zhifang's ability level is worthy of recognition. It is said that he has also joined the R&D team."

"but……"

He said with a twist in his voice, "They chose the wrong direction. Nickel-iron alloy? There is no prospect! There has been no progress for many years. It is impossible for them to produce results as soon as they do it."

"Are you right?"

…

A week later.

Zhao Yi, Zhang Hongtao, Wang Zhifang and Shen Binghe visited the 307 Steel Plant together. When they arrived at the airport, they were greeted by the staff of the steel plant. After entering the plant, they met He Guilin.

He Guilin is the leader of the aviation research and development team, and he must be invited to entertain the relevant 'expert group' when they visit.

The year before last, a group of experts from the Academy of Sciences also came to visit, and He Guilin entertained once. This time there were fewer people. He was very familiar with the work, but he didn't expect that Zhao Yi was among the expert groups.

"Zhao Yi, Academician Zhao?"

He Guilin opened his mouth in surprise, then remembered that he didn't look at the list of people carefully and just signed and waited.

But I was just surprised to see Zhao Yi. He still performed his duties as a 'tour guide' normally, explaining to them the manufacturing process of nickel-iron alloy, the material of turbine blades, and taking them to visit the large workshop at work, as well as the high-temperature furnace and condensation chamber. Waiting for equipment, I also looked for opportunities to inquire about the research and development issues of turbine blades by the 'expert group'.

There is nothing to keep secret.

"We are doing research on improving nickel-iron alloys, and we have just started. We just came here to visit." Wang Zhifang said directly.

He Guilin asked in surprise, "Isn't it single crystal nickel?"

Wang Zhifang glanced at Zhao Yi with depression, and said feebly, "Isn't there another institution doing monocrystalline nickel?"

He used this reason to convince himself that he decided to join the research and development project.

Of course, the most important thing is that he is very interested in the research of turbine blades. Even if he can't produce any results, the opportunity is not to be missed.

He Guilin noticed Wang Zhifang's eyes and knew that the 'expert group' was led by Zhao Yi. He was not surprised because Zhao Yi was so famous and influential, let alone an expert group on alloy materials, even if it came to philosophy. The research team is estimated to have become a core figure, and it is not strange for Zhao Yi to cross fields.

To his surprise, Zhao Yi decided to study 'improved nickel-iron alloy' instead of single crystal nickel direction.

"Isn't this a bit amateurish?"

"Improve nickel-iron alloy? If it could be improved, wouldn't we have achieved results long ago!"

He Guilin was a little confused.

The visit lasted for two days.

The actual tour only lasts four to five hours, and the rest of the time is spent waiting for the manufacturing process. For example, there is a high-temperature smelting furnace, and it takes more than an hour to activate the 'ultra-high temperature state' because the demand is not that high and only one can do it every week. It is activated once, and it is enough to maintain the high temperature at other times. The 'ultra-high temperature state' cannot be activated for the expert group to visit, but to maintain normal production status, they have to wait.

Among the four members of the ‘expert group’, Zhao Yi and Shen Binghe were visiting the steel plant for the first time.

Zhang Hongtao has been to steel plants several times, but has very little experience and doesn’t know much about actual production.

Wang Zhifang is very experienced. There are no unexpected parts in the manufacturing process of nickel-iron alloy. He only looks at some details carefully and asks specific questions. Because of this, he just looks at the whole process.

Zhao Yi and Shen Binghe had little experience at all, and even Shen Binghe was considered a 'pure layman'. Most of the time, he just listened to He Guilin's explanations and looked down at the information in his hands.

Zhang Hongtao had the most exchanges with He Guilin. He frequently asked questions related to R&D and manufacturing. Many of the questions always got to the point. He Guilin couldn't help but look at him with admiration and thought, "It would be great if such a young genius could join our R&D team." good."

Capable young researchers represent hope and possible future results.

He Guilin was very enthusiastic about Zhang Hongtao, and it was okay at first. Later, he felt that Zhang Hongtao was like the "leader", and the others were just supporting people. He was the one doing all the talking during the tour.

Zhao Yi, Wang Zhifang and Shen Binghe were all watching silently. Wang Zhifang felt great about Zhang Hongtao's ability, but Zhao Yi and Shen Binghe didn't react at all.

Zhao Yi did it because he didn't care.

Shen Binghe was walking at the end for a long time without any idea at all. He almost raised a sign and said, "Just soy sauce, passing by..."

He is just an incidental person and his participation in the project is 'passive'. What opinions can he have?

Two days later.

After inspecting the final cooled materials and walking around the R&D office building, the tour was almost over.

He Guilin exchanged greetings with Zhang Hongtao and sent a few people out. He also made a comment in his heart. He felt that Zhang Hongtao was a very capable young man with an unlimited future in the field of alloy materials.

Of course, Wang Zhifang doesn’t need to say much.

The old academician didn't say much during the whole process, but he can be recognized as an academician of the Academy of Engineering in the field of alloy research and development, and is also a pillar of materials science at the University of Aeronautics and Astronautics. There is no doubt about his ability.

Zhao Yi is just a layman.

Shen Binghe is like an assistant. He seems to know some alloy issues, but he doesn't seem to understand anything.

"It is said that Academician Zhao decided to study and improve nickel-iron alloy. I don't know why..."

"A layman commanding an expert?" He Guilin didn't understand, so he simply didn't think much about it. His work was over anyway.

The group of people walked to the main entrance.

He Guilin gave a symbolic greeting, "Thank you for visiting! You are all experts in the field of alloy materials. You have visited our production and manufacturing process. Do you have any valuable opinions to mention?"

Wang Zhixin nodded with a smile, waved his hand and said, "What are you experts on? Your technology is already perfect."

Zhang Hongtao said, “We are here to visit and learn.”

"Speaking of which, I do have a suggestion." Zhao Yi suddenly said something.

Others looked over immediately.

Zhao Yi said, "Team Leader He, I watched the whole process and found that there are many problems!"

He Guilin smiled awkwardly.

Zhao Yize continued, "However, regardless of the ratio, it is just a minor problem. There is one area where I think it can be improved. That is, when mixing ferrosilicon and ferronickel, you use a jump mixer. It’s back and forth, let’s not talk about this technology, but I think at this time, in order to prevent the temperature from dropping, we should continue the heating process to keep the process temperature constant.”

"After mixing, continue to maintain high temperature and perform deoxidation treatment directly and quickly without any intermediate steps."

After he finished speaking, he added, "That's the suggestion. You can try it. I think it should improve the performance of the final product."

He Guilin was a little stunned when he heard this.

He didn't expect that Zhao Yizhen would say something very detailed during the manufacturing process, and he didn't know how to react for a moment.

Zhang Hongtao reacted quickly and immediately followed, "Team Leader He, Academician Zhao is the real expert. His opinions are really valuable. You must try it!"

He also gave a special reminder, "Listen to me and try not to suffer a loss!"

"Okay, okay, definitely, definitely!"

He Guilin didn't know how to react, so he quickly nodded in agreement and sent several people to the car.
