The research and development of domestic turbine blades are optimistic about the direction of single crystal nickel, because "single crystal" is a new type of technology. It is very scientific to keep the elements and atoms that make up the alloy in a unified direction to increase the performance of the alloy.

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

Nickel has good plasticity, high polishing and corrosion resistance. Many alloy-related studies have shown that high nickel content helps to improve high temperature resistance and strength.

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

The road ahead has been passed, as long as we work hard and continue to move forward, there will definitely be results.

Inconel orientation is common.

Nickel-iron alloy has not improved for many years, and it is still a product of the past few decades.

If one distinguishes the direction of single crystal nickel from the direction of nickel-iron alloy, it can be said that single crystal nickel represents the latest alloy technology and research direction, while nickel-iron alloy belongs to the "traditional" technology.

Tradition seems to be eliminated.

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

Everyone thinks that the top turbine engine blades in the world are made of single crystal nickel alloy or that the entire turbine engine is made of single crystal nickel alloy. In fact, this is not true. The parts that actually use nickel alloy are actually some special places.

Accounted for the entire aero engine, but not even 10%.

People think that the cost of an F119 aero engine is 2000 million US dollars, so it is normal to use a single crystal nickel alloy.But in fact, the Chinese people think too well of the Americans. Pratt & Whitney is not a charity, and it is really a big joke to sell it to the Air Force at the cost price.

In fact, although the cost of the F119 aero-engine is expensive, one unit is equivalent to the unit price of China's purchase of aero-engines from Russia.

As the materials have completed the theoretical verification, after confirming that there is no problem, they will enter the stage of manufacturing samples with the materials.

The 404 steel factory, like other factories named after the code name, is also a non-public manufacturing factory, specializing in the production of alloy materials for domestic fighter jets, domestic aero engines and large-scale 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 aero engines. It can be said that its strength is very powerful.

In terms of strength, it is no worse than Xinjingang, Fushun Special Steel, Yingliu, AVIC Hi-Tech, and Gangyan Gaona.

Although the 404 Steel Plant is a national defense enterprise, the R&D department of the 404 Steel Plant is very embarrassing, especially the R&D team of some high-tech materials, which is so embarrassing that there is no sense of existence.

Decades ago, the steel products, products, and technologies produced by 404 Steel Plant came from the internal R&D group, which was equivalent to doing R&D and production by ourselves. Unable to meet the demand for materials in the aerospace field, steel mills had to use the results of outside scientific institutions.

This makes the existence of the aerospace material research and development group very awkward.

If the production of materials in the aviation field uses the results and directions of research and development by external institutions, they will become meaningless. However, it is a fact that the 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 jets did not have such high requirements for materials, and it was relatively easy to develop materials.However, with the development of the world, all kinds of advanced weapons are also advancing by leaps and bounds, and they are applied to many advanced materials, and the research and development of these materials requires a lot of investment. In the past, the country was poor, and scientific researchers could not even pay their salaries on time, let alone enough. So much research funding, so that in a difficult environment, material research can be said to be stagnant.In recent years, the country has money and began to increase investment.

But here comes the problem. The cultivation of personnel does not happen overnight. Many old experts are also groping alone, and it is not so easy to recruit talents, because they are not very attractive to talents, and they are more willing to go to other research institutes and scientific research institutions.

Therefore, Zhao Zhenhua, an expert in aviation materials of the 404 steel plant, is always worried about this matter. The aviation material research and development group will be abolished. After all, their aviation material group has not had a breakthrough in material research and development for seven or eight years, and the steel mill has invested a lot of money to update research and development equipment and production equipment, and has high hopes for the aerospace material group.

Zhao Zhenhua also knows that talents are the most important thing, but the 404 steel plant is not attractive enough for talents. Most of the truly capable talents choose to work in universities, science academies or scientific research institutions of enterprises. After all, these places have better remuneration and better working environment. It's loose, unlike the 404 steel factory where many people have to sign a confidentiality agreement, and they can't disclose a word after returning home. It's even normal to not go home after working in the unit for a year and a half.

The result is that there are not enough talents. Zhao Zhenhua is also a clever woman who can't cook without rice. He is tossing around with seven or eight big cats and kittens, trying his luck and seeing if he accidentally makes great achievements.

"Ah~~" Zhao Zhenhua sighed, thinking about how good it was decades ago, even if it was only a few dozen yuan a month, everyone was very passionate, willing to sacrifice themselves for the cause of the motherland, and they were a brick of the revolution. Where do you need to move.

But now, young people are realistic. They don't have to have both fish and bear's paws. They want to eat both fish and bear's paws, and they have a good appetite.

Are you unwilling to give good treatment?Then I will choose a unit with good treatment.

"Dinglingling~~" At this moment, the red phone on the table rang. As a unit with a high degree of secrecy, they were not allowed to bring communication equipment when they came in. Mobile phones and other things were handed over to the safekeeping office.

"Hi, I'm Zhao Zhenhua!" Zhao Zhenhua picked up the phone.

"Academician Zhao, Academician Liu from Shuimu University is calling you, is it connected?" A girl said, the call from the outside unit is not directly to the person, but needs to be transferred.

"Come in!" Zhao Zhenhua wondered why Academician Liu called him. Speaking of which, he was still a student of Academician Liu, but after starting work, the two of them could not meet twice a year.

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

"I'm Zhao Zhenhua!" Zhao Zhenhua said, being able to connect to his phone shows that the steel mill has ensured that the other party's identity is fine, otherwise it will be serious dereliction of duty and will be held accountable.

"Zhenhua, it's me! It's like this. Our Aeronautical Research Institute has made breakthroughs in material 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.

Eight types of materials are involved in the aero-engine this time, and corresponding units have been arranged for the other five types.

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

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

But in his heart, Zhao Zhenhua didn't have any hope. There were at least four companies in China that had better scientific research capabilities in the field of aero-engines than the Aero-Engine Research Institute of Mizuki University. It was not easy to make a name for themselves.

Now Academician Liu even told him that sample manufacturing and experiments are already going on.

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

"That's it." Zhao Zhenhua pondered for a while, he knew that Academician Liu was a person who pursued truth from facts, and he would never cheat: "I have no other arrangements recently, you can come here anytime!"

These are all confidential, and will never use emails or USB flash drives, and will not be brought by others. They are all done by themselves to ensure nothing goes wrong.

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

On the other side, at the Aero Engine Research Institute of Shuimu University, academician Liu and his brother joined together, and each of them led their team to a different factory.

Once their experiment is successful, the next step must be to build a prototype of an aero-engine for testing.

The research and development of aero-engines is very prudent. We will not manufacture a prototype at once and then slowly discover problems. Because it is a laboratory product, a normal aero-engine is manufactured for two to three million U.S. dollars. This is for Huaxia. Words are too extravagant.

After the step-by-step tests verify that there is no problem, the aero-engine prototype will be produced, and the running test will be carried out, and then the test parameters will be compared with the design parameters. According to the data, analysis, correction, and optimization will be carried out to ensure that there are no problems before the aero-engine will be launched. It will be carried on a fighter jet for flight test.

If an aero engine with a serious problem is directly put on a fighter plane, it will easily cause an aviation accident and cause a tragedy of aircraft crash and death.

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

As for the leakage of materials, Qin Yuanqing is not worried at all. The country still has basic morals, and it will not be so ugly when it is popular. It is not a Western country, and it will lose face.

Qin Yuanqing was 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.

It's just that Qin Yuanqing already knew it in his heart, no matter how fast, it would be very good to be able to manufacture samples of the engine for testing this year.
