It's still the simplicity of the people of this era!

There is not so much flashiness, nor so strong vanity, and they are down-to-earth and at ease in their own work to do practical things, which is the common characteristic of most of them.

Yang Weiping sighed in his heart, beckoned Sun Yuanzheng and Liu Qinghe to sit down, and discussed the next research work of single crystal alloys.

Through conversation, Yang Weiping learned that Sun Yuanzheng also inadvertently found that after adding rare earth elements to the single crystal alloy, there were obvious changes, and then according to this idea, after repeated proportioning and experiments, it took nearly ten years to complete the mature formula and preparation process of this nickel-based single crystal alloy.

In other words, some domestic research institutions are likely to have begun research on rare earth elements.

As long as various scientific research units begin to pay attention to rare earth elements, then he can justifiably list China's rare earth as a national key strategic resource!

The Commission of Science, Technology and Industry for National Defense happens to have privileges in this regard!

"Director Sun, I have also done some research on single crystal alloys. Yang Weiping said seriously: "It is precisely because of this that I attach great importance to single crystal alloys." I have been working on single crystal alloys in the Tiangong laboratory in Switzerland.

In my opinion, the three elements of pair, b, and hf can be considered from the previous 'complete removal' to 'limited use'. For the four refractory elements of TA, RE, and , the total amount of them can be added appropriately.

I've just heard from you that you've increased the mass fraction of these four refractory elements to 169% of the total, and I think it can be increased a little bit more, to about 27%. The proportion of the RE element can be increased a little. Because this can balance the alloying, it is necessary to put and properly lower the bottom.

In addition, you can also try to increase the amount of AL by a certain amount. r, if possible, it is best to control it below 5%!"

Elder Sun Zheng frowned deeply and asked: "Director Yang, if the content of R in the alloy is less than 5%, the oxidation and corrosion resistance of the alloy will deteriorate to an impermissible extent. ”

Yang Weiping smiled and nodded, "Normally. A lot of people have this view of yours. However, this view is not absolute. Although R is an anti-environmental corrosion element, because the composition of all elements of the alloy has a limit, reducing the content of R can increase the content of TA and RE, so as to ensure the stability of the alloy structure and improve its comprehensive properties. ”

"Well, theoretically. This ratio is also established, but it takes experiments to know whether it is effective. Sun Zhengyuan nodded thoughtfully and said.

Just do it, it has always been Yang Weiping's style.

As a result, Yang Weiping followed his trend in the development of nickel-based single crystal alloys in later generations, and cooperated with Sun Zhengyuan and Liu Qinghe, and immediately launched a new ratio experiment.

Through experiments, Yang Weiping found that Sun Zhengyuan had mastered a directional solidification, hollow, and no-margin casting process for turbine blades.

This is a combination of directional solidification technology, complex air-cooled hollow core manufacturing technology, no margin precision casting technology in one, very practical advanced blade casting technology! This is definitely a breakthrough in the manufacture of turbine blades!

Sun Zhengyuan: They are really amazing! They have not only achieved results in the preparation of nickel-based single crystals. At the same time, it is also exploring and researching the manufacture of turbine blades, and has successfully summarized a unique advanced and practical new process.

Besides. Yang Weiping also saw two large-scale five-axis linkage CNC turning and milling machining centers manufactured by Huhai Machine Tool Factory in the Seiko workshop of this research institute.

This discovery made Yang Weiping feel that this trip to Chang'an was really worth it! He finally understood why Lin Jianfeng and Xu Gensheng would put a black hat of "molten gold cave" on this research institute.

In the eyes of outsiders, the research expenses and various equipment invested by this institute are indeed very large, but the economic benefits generated are not very obvious.

It has been less than 20 years since the project was established in 195. With a total investment of 470 million Chinese dollars, the annual cost is more than 20 million Chinese dollars, which is for a research institute. This was indeed a very large investment in Huaxia at that time.

Only Yang Weiping can really know that the accumulation of skills in this research institute simply cannot be measured by money!

Considering the current political situation in China, Yang Weiping promptly changed the name of Chang'an Semiconductor Materials Application Research Institute to Huaxia Chang'an Aviation Power Materials Application Research Institute, codenamed 9, directly under the vertical leadership of the Commission of Science, Technology and Industry for National Defense.

In the last life, in order to make the nickel-based single crystal alloy in China, Yang Weiping conducted repeated and detailed research and analysis on the samples of the two third-generation nickel-based single crystal alloys of -1 and renen6 in the United States, and calculated the various element components in these two single crystal alloys.

In this experimental ratio, Yang Weiping listed the relevant proportioning data of the two third-generation nickel-based single crystal alloys known to him, -1 and renen6, and handed them to Sun Zhengyuan and Liu Qinghe.

This new formula suddenly made Sun Zhengyuan's eyes light up. Combining his nearly 20 years of experience and experience, he adjusted the ratio of this new formula slightly so that it could be combined with the preparation process of the nickel-based single crystal alloy he named DZ5G, and applied it to this technological innovation.

With Director Yang personally sitting in the research institute, of course, the funds and various raw materials will be provided as much as they want.

The original 36th Bomber Division Headquarters Police Company is now officially included in the guard company of Huaxia Chang'an Aviation Power Materials Application Research Institute. This is the result of Zeng Qingyuan and Fu Jianjie's initiative request. Because, in the words of the two of them, the future of the Huaxia Air Force is in this research institute, and all officers and men of the Air Force have the responsibility and obligation to protect this place with their lives.

After nearly half a month of repeated experiments and adjustments, on this day, a new type of nickel-based single crystal alloy was put into mass production for the first time in the constant temperature workshop.

Yang Weiping watched nervously and inexplicably, Sun Zhengyuan pressed the power switch of the production line. Without blinking, the operating technicians and technicians stared closely at the raw materials through the selection, into the process of making seed crystals, and then into the crystallization process, and then in the electron beam area melting method to cultivate naturally grown single crystals, and then after the light orientation test, through laser wire cutting to cut the seed crystals.

Cut the seed crystals and grind them. Polishing, corrosion, light directional re-inspection, into semi-finished seed crystals, into directional solidification vacuum furnace, and finally into alloy rods.

During the third light-oriented inspection of the alloy rod, Yang Weiping was so nervous that his palms were sweating.

"The qualified product has reached 5%! Director Yang, we have succeeded! We have successfully prepared a temperature of 627 degrees Celsius. The third-generation nickel-based single crystal alloy with a density of 9!" Sun Zhengyuan held the test report in his hand and excitedly raised it towards Yang Weiping.

Yang Weiping rushed over to take the test report from Sun Zhengyuan, and then hugged Sun Zhengyuan tightly, an old man and a young man jumping and jumping like two children.

"It worked!

"We have created a miracle! This will be the most advanced third-generation nickel-based single crystal alloy in the world!" Yang Weiping shouted like a madman while jumping and jumping: "The wisdom of the Chinese nation is invincible!

"We succeeded!"

A cheer kept shouting from the mouths of the researchers and operation technicians in each process, and everyone couldn't help but hug each other uncontrollably, waving their work hats in their hands, jumping and cheering.

After more than ten minutes of cheering and celebrating, Liu Qinghe wiped the tears from the corners of his eyes with his sleeve. His hands pressed together again and again, and he shouted loudly: "Comrades. Everyone welcomes Director Yang's instructions!"

"Whoa, whoa, whoa, ......whoa," and the warm applause rang out.

Yang Weiping wiped the excited tears on his face with the back of his hand, and took several deep breaths in succession before trying to calm himself. He climbed onto a fitter's workbench, looked around at the 67 staff members in the workshop, and after the scene was quiet, he raised his voice and said: "Comrades! You have once again proved to the world that we Chinese people are the best nation in this world. The crystallization of the wisdom of the Chinese people is incomparable! Because, following the four great inventions of the ancient Chinese civilization, we have once again created a miracle. It has become the first in the world!"

The deafening applause of "Whoa, Whoa, Whoa......" thundered like a tide.

"On behalf of all the members of the Party Committee of the Commission of Science, Technology and Industry for National Defense, I would like to express my heartfelt thanks and congratulations to you!" Yang Weiping said in a passionate voice: "I want to ask the Party Central Committee and the No. 1 Commander for your credit!"

"Whoa, whoa, ......whoa, whoa," the applause roared again.

"Comrades, although you have achieved tremendous results, this is only a small step in the great cause of the rejuvenation of the Chinese nation. Yang Weiping clenched his right hand into a fist and bent his elbow in front of his chest, and said in a particularly loud voice: "I hope that everyone can guard against arrogance and dryness, be more strict with themselves in the future work, and strive for new heights on the basis of existing achievements!"

The Third Plenary Session of the 11 th CPC Central Committee has already proposed to the people of the whole country that the four grand goals of socialist modernization should not be realized in this century. At present, the CPC Central Committee and the State Council have demanded that the pace of realizing the four modernizations be quickened, and a series of policies and organizational measures have been formulated to this end.

The Central Committee pointed out that the current reform of the economic system is a great revolution that will fundamentally change the backwardness of China's economy and technology and further consolidate the dictatorship of the proletariat.

Therefore, all economic fronts need to carry out major technological innovations not only but also major institutional and organizational reforms. Carrying out these reforms is in the long-term interests of the people of the whole country, otherwise, we will not be able to shake off the current backward state of production technology and production management.

Commander No. 1 has said that intellectuals are a member of the working class and an important part. The Central Committee believes that for the sake of socialism with Chinese characteristics and the interests of the four modernizations, the working class throughout the country will certainly play a role as an exemplary vanguard of selflessness in these reforms.

One of the most important characteristics of the working class is its association with socialized mass production. Therefore, your consciousness is the highest, your discipline is the strongest, and you will certainly be able to play a leading role in the economic and social and political progress of the present era.

I sincerely hope that you will unite as one to master the modern technical knowledge and modern management knowledge with the greatest efforts to master the modern technical knowledge and modern management knowledge, and make outstanding contributions to the realization of the four modernizations.

The more anyone contributes to the four modernizations, the more honors and rewards the state and society will give him, and this is a matter of course.

The Party Central Committee and the State Council have decided that in order to commend the advanced and celebrate the 30th anniversary of the founding of the People's Republic of China, they will prepare to hold a meeting next year to fight hard in the production of 15 Ping's jealousy of the People's Republic of China.

"Whoa, whoa, whoa, ......whoa," thundered and the applause of the pan continued for a long time. Everyone in the workshop was more excited, enthusiastic and enthusiastic at this moment than when they celebrated the successful launch of the new product on the production line.

Yang Weiping really didn't expect that the group of unknown scientific researchers and technical workers led by Sun Zhengyuan and Liu Qinghe successfully developed a new nickel-based single crystal alloy named DZ5H in such a short period of time after digesting and absorbing the two formulas he gave.

The temperature of the DZ5H was increased to 627 degrees Celsius, and the density was also increased to 9 grams per cubic centimeter. This is slightly stronger than the third-generation nickel-based single crystal alloy researched by the Americans in later generations, in terms of increasing temperature and density.

With this secret weapon in his hand, Yang Weiping is even more convinced that when improving the AL31 engine provided by the Soviet Union, it is entirely possible to get the AL31NF type out in advance.

High-temperature titanium alloy, high-strength titanium alloy, high-temperature aluminum alloy, high-strength aluminum alloy, nickel-based single crystal alloy, the five most important alloy materials are available, and the next only need to improve the precision machining technology, China's aero engine business will surely usher in a new era!

9 Seiko workshop in the two sets of five-axis linkage CNC turning and milling machining center, Yang Weiping personally tried, in the CNC program, the French really did not hide privately, actually used five degrees of micro computer numerical control system, but also retained the program upgrade and upgrading interface.

In terms of measuring equipment, all of them are self-developed precision tools: tool microscope, one-point goniometer, 14 Yi Wonton and just 9 x nephew tenacious 2 17 lazy new frame 17 lazy end carry said magpie to?

From these two five-axis linkage CNC machine tools, Yang Weiping can be sure that Huhai Machine Tool Factory has invested much more in the manufacture of precision machine tools than in the research of single crystal alloys in 9 institutes.

We must immediately go to the Huhai Machine Tool Factory! We must know that Huhai was once a major disaster area of turmoil, and in this wave of investigation and liquidation, it is also the big city with the strictest investigation and the widest range of involvement.
