Chapter 217 Mu Yang's Fantasy (Order)

Mu Yang silently opened the reading system.

achievement point shop,

Search for "aero titanium alloy" silently.

In an instant, hundreds of technologies appeared before his eyes.

Then screened out the manufacturing process recipes of aerospace titanium alloys, and only thirty or forty kinds remained.

Aerospace titanium alloys have different structures and parts, and the types of titanium alloys used must be different. There are probably several types.

For example, rivets must have excellent plasticity. Generally, pure titanium is used instead of titanium alloys; if the strength is very high, how can the rivet move? It will crack when pulled.

Another example is bolts, which require high strength and toughness inside, that is titanium alloy TC4.

Mu Yang wanted to find TC4 first, which is a medium-strength two-phase titanium alloy, and it is also the most researched and applied titanium alloy material. Most of the titanium alloy materials used for compressor blades, disks, and fasteners are this material.

After looking for a while, he quickly found the craft formula he wanted.

"Manufacturing process and formula of a new aerospace titanium alloy TC4"

[Introduction: A new alloy formula, using unconventional hot heading equipment and heating equipment, and a new heat treatment method, greatly improving production efficiency and material utilization... The tensile strength of the alloy after solid solution aging can reach up to 1300 MPa, which is higher than that of conventional alloys. Military aviation TC4 is about 18% superior, and has good toughness. The hardenability of titanium alloy reaches 25mm, which is 19mm beyond the conventional technology.]

After reading the introduction, I found that there is currently only one version to choose from.

It is also easy to understand that an alloy formula corresponds to a technology.

[TC4 1.0, the world's top level, price: 20 achievement points]

[Subject requirements: steel heat treatment level 5, material technology and equipment level 5, modern material testing method level 4, material science foundation level 5, metallurgical engineering level 5, material mechanics level 5, advanced mathematics level 5, titanium and titanium alloy level 5 class……】

Although there are not many achievement points required, if you want to finish all the aerospace titanium alloys, you need to purchase several crafting formulas.

After Mu Yang read the introduction, he didn't require level 6 subjects, but twenty or thirty subjects, most of which required level 5. This type of formula mainly depends on inspiration, and it comes to mind when you think of it. The chance of experimentation is very large.

People who have experimented with material formulas and medical formulas know very well that it depends on countless experiments, and the chance of success is very high.

Of course, there must be enough knowledge, otherwise the general direction is wrong.

Mu Yang has accumulated a lot of experience. For the subject requirements of TC4 1.0, what he lacks is only a few subjects that have not reached the level.

Upgrade subjects!

He marked all the subject requirements green, and then clicked to buy.

After purchasing, absorb the knowledge.

Suddenly, his head swelled, and he felt a lot of knowledge and memory about the manufacturing process of titanium alloy flooded into his mind, including the chemical composition and percentage of TC4, how to prepare it, casting process, heat treatment process, and the fabric ingredient process of sponge titanium ...and the requirements for supporting equipment for manufacturing it, the size of the proposed factory building, how to plan...

After a few minutes, Mu Yang's absorption was completed.

After finishing this, Mu Yang will buy another titanium alloy TA7

"Manufacturing process and formula of a new aerospace titanium alloy TA7"

[TA7 1.0, the world's top level, price: 20 achievement points]

The manufacturing process is of course different, TA7 and TC4 are not the same subclass.

The main alloying elements of TA7 are aluminum and tin, and its strength is not as high as TC4, but it has good low-temperature impact toughness, and its plasticity is much better. It is suitable for stamping parts with complex shapes, and can also be cold deformed.

If you use TC4 to make parts with complex shapes, it will definitely not work, and cracks will easily appear. Just like a household utility knife, it is easy to break when bent at a certain angle, because its plasticity is relatively poor.

The disciplines required for this craft formula are basically the same, and Mu Yang spent another 20 achievement points to buy and absorb it.

All of a sudden, he mastered the process formula and manufacturing method of the new TC4 and TA7, which can almost cover aerospace titanium alloy materials.

Learn this thing well, but if you want to manufacture it, you mainly rely on equipment.

For example, the casting space in a vacuum environment can only be put into use for equipment and manufacturing after the new headquarters and new factories are put into use.

However, preparatory work can also be done at present. In fact, the production workshop of titanium alloy does not need to be very large.

How much is the global demand for a year?

More than 40,000 tons!

Mu Yang estimated that he got 4,000 tons, which also occupied a large market.

More than 4,000 tons, if it is ordinary titanium alloy, its market price is only 150-280 yuan/kg, and the output value is 600 million-1.12 billion yuan.

But what did Mu Yang make?

Aviation titanium alloy, moreover, about 18% superior to conventional aviation TC4! And the toughness is stronger.

The current market price of aviation titanium alloy is 500-1300 yuan/KG, and it is difficult to buy domestically.

The individual performance is 18% stronger, but the overall performance is not just 18% stronger.

Mu Yang estimates that the overall mechanical performance is about 25% stronger, which may be about 10% higher than the same model TC4 of the world's top titanium alloy manufacturer.

The technical performance of the TA7 he bought is similar, and it is estimated that the overall mechanical performance is about 10% higher than that of the same model TA7 from the world's top manufacturers.

If it is to be sold, it is not that the price is only 25% higher, and it is not too much to be twice as expensive as conventional military titanium alloys.

Of course, for example, the top-notch titanium alloy sells for 1,300 yuan/KG, which is 1.3 million yuan per ton. The overall performance of his titanium alloy is 10% higher, and it can be sold at this price for the domestic market, or a little lower. He is also very profitable. After all, his manufacturing cost may be less than 150 yuan/KG

For foreigners?

Not for sale!

Even if he wanted to sell it, the country would not allow him to export it.

How much is the specific amount of titanium alloy used in the aircraft?

Assuming that it is 1300 yuan/KG, a C919 is 9.0%, corresponding to 3.8 tons of titanium for a single frame.

The SR-71 Blackbird reconnaissance aircraft with an empty weight of 30.6 tons uses more than 73% titanium, and the amount reaches 22.3 tons.

However, the cost of titanium alloy materials is not a high proportion compared to the cost of aircraft exceeding 100 million yuan.

Therefore, even if it is calculated based on 1,000 yuan/KG, the annual output is 4,000 tons, the output value is 4 billion yuan, and the gross profit may reach 3 billion yuan.

Of course, maybe this is a very ideal algorithm.

The world is changing, and he doesn't know what the future holds.

Turning back to the topic, the amount of 4,000 tons is really not that big.

Calculated according to the density of 4.5g/cm3, the total volume is only 889 cubic meters!

The required production equipment covers an area that is not very large compared to a steel factory, mainly because there are more technological processes and more equipment, and 20 mu of land is enough.

Mu Yang can completely manufacture and produce in the new headquarters factory by himself, and does not need to authorize the technology to domestic titanium steel factories, and at the same time can ensure the confidentiality of the core formula. When I need titanium alloy to make aviation aircraft in the future, it will be more convenient to use materials.

However, if the formula is kept secret, it will be difficult to earn achievement points through invention patents. I hope to earn them back from other places.

But in any case, this is an infinitely bright career.

Mu Yang combed through the titanium alloy, squinted his eyes, and soon fell asleep.

He had a sweet dream, dreaming that he was flying in space in his own spaceship, and there were only him and Song Xuelu on board, and they were doing indescribable movements.
