Basic materials are the key to the development of all mechanical technology equipment, especially some very important top-level materials.

These materials cannot be careless at all. Liu Yijiu knew what these people thought, first came up with one to solve the current difficulties of use, and then slowly came up with the same and continuously improved. This is the path taken by various countries, so that a lot of experience and technology can be accumulated.

But he can't wait.

To prepare for the next fighter jet, we must work hard on high-temperature alloys. The Republic's aviation industry was largely limited by this material. The research work of Turbofan 6 has been over. If Yang Wei and the others had not stolen the Tu-22m2 backfire from the Russians, the fate of this team would have been as split, and then partly went to the large aircraft factory in the Shanghai Stock Exchange, partly partly entered Qinfei, and the other part entered Shenfei.

Now, after the measurement of the backfire bomber is completed, they will start a new generation of engine research. The Russians are far from comparable to the Chinese in terms of engine technology. Even Americans are even worse than the Russians in this regard.

This engine technology is based on advanced high-temperature alloys.

The working temperature is very high, and the working conditions are extremely harsh and the service life must be very long. This is not a problem that the 760°c high-temperature alloy in the Republic has touched the threshold. If this alloy is made of an engine, its service life will not exceed two hundred hours.

The cost of an engine will be millions of dollars. In this case, the produced engine will cost the aircraft more than 10,000 US dollars in terms of engines alone. This is a twin-engine heavy fighter. A single-engine engine costs 5,000 US dollars per hour!

How can the poor Republic Air Force afford such high flight costs?

Liu Yijiu discussed with Zhao Maoping all the way and soon entered the research workshop where Jia Yiming was. This workshop is the largest base in the entire second area. It not only has a complete physical and chemical analysis room, but also has various process equipment from the beginning to material sintering and forming.

"Teacher Jia, what's wrong with you? How many days have you not had a rest?" Liu Yijiu didn't have much time to see Jia Yiming now. The old man was in District 2. His original dormitory was in District 3, and his son was in the school in the base. The accommodation was there. Jia Ling entered the gun research and design room in District 3, but he settled in District 2.

"You are here? I have been thinking about how to improve the purity of various materials. There is no problem with these materials that are chemically purified. The key is that it is not possible to use smelted materials now." Jia Yiming did not regard you as an ordinary technical researcher.

Shi Changxu was also very successful in high-temperature alloys. After Yao Tongbin was beaten to death, he and his research team were working on the top materials needed in aerospace in the entire Republic.

"If we want to produce cannon steel, we must use this furnace to re-smel the extracted materials again, so that the steel obtained will further reduce impurities..." Liu Yijiu sighed.

At first, he was so busy that he forgot to reorganize the electric slag furnace. Wang Shunyi was also busy working on his missile project all day long. He wanted to create a better missile. So he forgot that Zheng Hao was not in the base at all, so he could not count on him.

Originally, Liu Yijiu believed that there was no technology in China. When he knew that the Shanghai heavy machinery factory had production technology in this area since the 1960s, he was always thinking about when he would come back from there to build a set of electric slag furnace production equipment.

Without this thing, their new gun steel would not be able to be produced.

"Can that thing really work?" Jia Yiming obviously didn't believe this. There was no such material provided by Liu Yijiu in China. He got it from where. Jia Yiming was too lazy to ask. As long as he could get the materials out and make some domestic research progress accelerate, he would be satisfied.

"Why is it useless? Tank gun steel is purified by remelting the electric slag furnace, so that the performance can be about twice as high! Don't our domestic 541 and 617 use this technology? Since there are many impurities in the new gun steel, this method can be used to further purify..." Liu Yijiu was a little confused. Will Jia Yiming and others make such a mistake?

Hearing his words, Jia Yiming suddenly patted his head and said in annoyance: "If I had known this, I would no longer have to use chemical treatment methods to obtain these material elements..."

Liu Yijiu rolled her eyes when she heard this.

Such a top-level big shot would make such low-level mistakes?

Is this a bit incredible?

"When the New Year comes, we will send people to the Shanghai Stock Exchange and get a set of equipment from there. Let's try it out again. The Chinese New Year is coming soon, and it is probably a holiday there. It's useless to be anxious. We should do other theoretical research work first, especially designing the equipment we need in high-temperature alloys. Not to mention the price, we don't have foreign exchange at all! Moreover, they all know what these things are for, so they will naturally not be polite to us..." If we want to introduce high-temperature alloy powder metallurgy process equipment, even because we are in the early stage of honeymoon period in Chinese and Western countries, Liu Yijiu will not have much hope.

High temperature alloys are necessary for aerospace. Without this thing, jet engines cannot be made.

There are already many research results on high-temperature alloys in China, but the materials of these high-temperature alloys have no way to make the engine have a higher service life. High-temperature alloys used in intercontinental missiles are enough to use them in less than an hour at the working temperature of the rocket engine, and at most, it is more than an hour. Generally, high-temperature alloys can achieve such performance.

Aircraft engines are different, and this requires repeated use. In this way, the material requirements of this aircraft engine are much higher than that of rocket engines.

"Why are you waiting for the New Year? Let's go there now! Their New Year shouldn't be on holidays, right? The whole country is in trouble!" Jia Yiming has not worked for many years. Now, after he started to resume work and had adapted for a while, he devoted himself to it.

Just like the others in the base, they were wasted too much time.

"If we don't have holidays here, it doesn't mean they don't have holidays. If there are not enough production tasks, their daily work may not be full..." Liu Yijiu knew that the situation of this factory is not very good now.

The country has not invested very much in the aviation industry, especially many aviation projects are now facing the dilemma of dismantling.

Liu Yijiu chatted here for a while, and now he didn't dare to reveal some materials, craftsmanship and formulas. On the one hand, it was to prevent Jia Yiming and the others from exhausting themselves, and on the other hand, it was to prevent himself from revealing too much, and he could not explain the source of many things.

It was simply unreasonable to rely on his teachers. He made it out of the things that his teachers hadn't made, and he didn't see any experiments or research he did. In the end, what else could others say when they smelled? It couldn't explain.

Just like his teacher, Mr. Qian Xuesen, is also an expert in nuclear physics, this is only known to a few people. Outsiders only know that he is an expert in missiles. Liu Yijiu's other teacher, Zhu Guangya, highly praised him.

Can someone who can discuss the truth with Zhu Guangya have no achievements?

The book "Cybernetics of Engineering" written by Mr. Qian at that time was admitted to be a heavenly book!

People who don’t know how to master these professional knowledge can’t be mastered at all.

"But, without these materials, our engines would not be able to be used at all. The missiles are not a problem, but the problem is the aircraft? Unless we do not engage in aircraft engine projects, the turbofan Six project team is because the materials have not been able to make progress, so..." Zhao Maoping was also very concerned about this matter.

Their ambitions are now expanding to the direction of getting key materials for the aircraft engine.

They know better than anyone else how strong the Republic has for new aircraft.

"This matter cannot be solved in a short time. Anyway, the WT6 team is still continuing to make the WT6 in Rongcheng. If you want to get the Tu-22 engine, you can't start it in less than half a year to a year..." Liu Yijiu sighed.

He is more anxious than anyone else.

The sooner these technologies are produced, the less arrogant the United States will be after the collapse of the Soviet Union.

If he dared to drive the aircraft carrier to conduct military exercises at the door of the Republic, then the Republic will directly dispatch a group of bombers and fighters with low-altitude supersonic penetration capabilities to exercise in that area, flying over their aircraft carriers, and seeing if the Americans can wet their pants.

The Republic pursues a defensive strategy and will not take the initiative to attack any country.

"How long does it take for our new aircraft to get into the sky!"

"This is a matter of no choice. If you have the opportunity to make it out, it will be almost done. Isostatic pressure equipment must be made out first, and large high-frequency furnaces and vacuum induction furnaces must also be made out. In the future, we will develop various high-hardness and high-strength materials, except for powder metallurgy. The melting points of various materials are different, and there is a way to melt some materials and eventually change their performance because other matching elements exceed the boiling point...
