Chapter 196 Material Samples

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 high 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 achieve results.

The direction of nickel-iron alloy is very common.

Nickel-iron alloy has not made any progress for many years and is still a product of 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 on the verge of being eliminated.

But now it is different. The formula of nickel-iron alloy can reach 1850℃~1900℃. This undoubtedly means that nickel-iron alloy still has a lot of room for development. Compared with single crystal nickel, which has high performance but is expensive, there is no doubt that nickel-iron alloy is the best choice.

More economical.

Everyone thinks that the world's top turbine engine blades are made of single crystal nickel alloy, or that the entire turbine engine is made of single crystal nickel alloy. This is actually not true. The parts where nickel alloy is actually used are actually some special places.

It accounts for less than 10% of the entire aircraft engine.

People think that the cost of an F119 aircraft engine is 20 million US dollars, so it is normal to use single crystal nickel alloy. But in fact, the Chinese think too well of the Americans. Pratt & Whitney is not a charity, and it really sells at cost price.

For the Air Force, that's a big joke.

In fact, although the cost of the F119 aero engine is expensive, one unit is equivalent to the unit price of the aero engine purchased by China from Russia.

After the theoretical verification of the materials has been completed and it is confirmed that there are no problems, the materials will enter the stage of manufacturing samples.

404 Steel Plant, like other factories with code names, is also a manufacturing plant that is not open to the outside world. It is a factory that specializes in producing alloy materials for domestic fighter jets, domestic aerospace engines and large equipment.

The 404 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 scientific research projects, including military weapons such as fighter planes, submarines, warships, tanks, and aerospace engines. It can be said that it is very powerful.

In terms of strength, it is no worse than Xin Jin Gang, Fushun Special Steel, Yingliu Stock, AVIC Hi-Tech, Steel Research and Gaona, etc.

Although 404 Steel Plant is a national defense enterprise, the R&D department of 404 Steel Plant is very embarrassing, especially the R&D groups of some high-tech materials, which are even more embarrassing to the point of "no sense of existence."

A few decades ago, the steel products, products, and technologies produced by 404 steel mills all came from the internal R&D group, which was equivalent to doing their 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 greatly improved.

Unable 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.

The world is changing very fast. In the past, fighter planes did not have such high material requirements, and it was relatively easy to develop materials. However, with the development of the world, various advanced weapons have also advanced by leaps and bounds, and many advanced materials have been applied to them. The research and development of these materials have

It requires a heavy investment. In the past, the country was poor, and scientific researchers could not even pay their salaries on time, let alone sufficient scientific research funds. So in a difficult environment, materials research can be said to be standing still. In recent years, the country has

Once you have money, start investing more.

But here comes the problem. Training of personnel does not happen overnight. Many old experts are also groping alone. Recruiting talents is not that easy because it is not very attractive to talents. People are more willing to go to other research institutes and scientific research institutions.

Therefore, Zhao Zhenhua, an aviation materials expert at the 404 steel plant, has always been worried about this matter. Although he was elected an academician a few years ago, he is still at a loss to solve the dilemma of aviation materials research and development. He is always worried that one day, the steel plant will

The aviation materials research and development group will be abolished. After all, their aviation materials group has not had any material research and development breakthroughs for seven or eight years, and the steel mill has invested a lot of money in updating research and development equipment and production equipment, so it has high hopes for the aviation materials group.

Zhao Zhenhua also knows that talents are the most important thing, but the 404 steel plant is not attractive to talents. Most of the truly capable talents choose to work in universities, academies of sciences or corporate scientific research institutions. After all, these places have better pay and better working environment.

It's relaxed, unlike many 404 steel plants where you have to sign a confidentiality agreement. You can't reveal a word after you go home. It's normal even to not go home after working in the unit for one and a half years.

The result is that there are not enough talents. Zhao Zhenhua is also a clever woman who can't make a meal without rice. He brings seven or eight big cats and kittens to mess around, trying his luck to see if he is not careful to produce big results.

"Alas~~" Zhao Zhenhua sighed, thinking about how wonderful it was a few decades ago. Even if it was only a few dozen dollars a month, everyone was very passionate and willing to sacrifice themselves for the cause of the motherland. They were a brick of the revolution.

Where does it need to be moved?

But now, young people have become realistic. They don't have to have their cake and eat it too. They want to eat both fish and bear's paw, and they have a very good appetite.

Are you unwilling to give good treatment? Then I will choose an employer with good treatment.

"Ding ding ding~~" Just at this moment, the red phone on the table rang. As a highly confidential unit, they are not allowed to bring communication equipment when they come in. All mobile phones and other items must be handed over to the safekeeping office.

"Hello, this is Zhao Zhenhua!" Zhao Zhenhua picked up the phone.

"Academician Zhao, Academician Liu from Shuimu University is calling you. Can you get through?" a girl said. The call coming from an outside unit was not directly to the person, but needed to be transferred.

"Come in!" Zhao Zhenhua was curious as to why Academician Liu was calling him. He was still a student of Academician Liu, but after he started working, the two of them could not meet twice a year.

"Is it Zhenhua?" Soon, a voice rang on the phone.

"I'm Zhao Zhenhua!" Zhao Zhenhua said. Being able to access his phone means that the steel mill has ensured that the other party's identity is correct. Otherwise, it will be a serious dereliction of duty and will be held accountable.

"Zhenhua, it's me! That's right, our Aviation Research Institute has made breakthroughs in materials research. High-strength steel, nickel-iron alloy materials and single-crystal nickel alloys need to be sampled and tested in your unit." Academician Liu said.

This time the aircraft engine involves eight types of materials, and corresponding units have been arranged for the other five types.

"Your research institute has made a breakthrough now? I remember that your aerospace engine research institute was established less than half a year ago!" Zhao Zhenhua was surprised.

When the Aero Engine Research Institute of Shuimu University was inaugurated, Zhao Zhenhua, as an expert in the field, also participated and witnessed the establishment of the Aero Engine Research Institute.

However, Zhao Zhenhua has no hope in his heart. There are at least four companies in China with better scientific research capabilities in the field of aviation engines than Shuimu University Aero Engine Research Institute. It is not easy to become famous.

Now Academician Liu actually told him that sample manufacturing and experiments were already underway.

"Yes!" Academician Liu gave a very clear answer.

"That's it." Zhao Zhenhua pondered for a moment. He knew that Academician Liu is a person who pursues truth from facts and will never cheat: "There are no other arrangements recently. You can come over at any time!"

These are all confidential. We will never use emails or USB flash drives, and we won't let anyone take them with us. We do everything personally to ensure nothing is missed.

It is not difficult for 404 steel mills to manufacture a sample and conduct a test, otherwise the country's heavy investment will be in vain.

On the other side, Shuimu University Aero Engine Research Institute, together with Academician Liu and his brother, led their teams to different factories.

Once their test is successful, the next step must be to build an aero-engine prototype and conduct tests.

The development of aero engines is very cautious. We will not build prototypes all at once and then slowly discover problems later. Because they are laboratory products, a normal aero engine costs two to three million US dollars to manufacture. This is very important to China.

It's really too luxurious.

Only after step-by-step testing and verification that there are no problems will the aero-engine prototype be produced and run experiments will be carried out. Then the test parameters will be compared with the design parameters. In this process, the data will be analyzed, corrected and optimized to ensure that there are no problems before the aero-engine will be produced.

It will be mounted on a fighter jet for flight tests.

If an aerospace engine with serious problems is directly installed on a fighter jet, it will easily cause an aviation accident, resulting in a tragic aircraft crash and fatalities.

Qin Yuanqing directly approved Academician Liu's application report, and he did not follow him. After all, Qin Yuanqing knew the result well, and the system's products would be high-quality products. Qin Yuanqing could still trust this.

As for the leakage of the materials, Qin Yuanqing is not worried at all. The country still has basic moral integrity, and it is not so ugly as to be popular. It is not a Western country, so it loses face.

Qin Yuanqing was somewhat looking forward to it at this time, whether the R&D team could optimize this process and come up with an engine with better performance than the American F119 aero engine.

But Qin Yuanqing already knew that no matter how fast, it would be very good to be able to produce samples of the engine for testing this year.
