During the Spring Festival, Liu Yijiu only took a few days off. Although he was drunk most of the time or on the way to drunkenness, the technicians and managers who were drawn out to research turboshaft engines were still working.

The tank research team and related project teams can celebrate, and the missile research team can go crazy. All of this is because the project has achieved phased success. The first batch of real arms sales orders in the base come from these two project teams.

There has been no progress in helicopters now, which means that they have been doing preparations all the time.

Although it is the plan demonstration stage, the plan basically adopts the solution of Z-7 and Mi-24, and there will not be too many problems.

The problem is various basic data.

"We need to develop a new type of aluminum alloy again? Director Liu, right? We already have an advanced aluminum alloy for aerospace." As for Liu Yijiu's project to develop a new type of aluminum alloy as a supporting project for the transformation of the Zhi-91 general-purpose helicopter code-named Zhi-91 general-purpose helicopter, Jia Yiming did not get the task before the New Year, but he did not expect that after the Spring Festival, Liu Yijiu asked him to start this matter.

He is now working on improvement projects for titanium alloys and nickel-based high-temperature alloys, and has now reached a critical stage.

Of course, the more advanced materials, the better, but the problem is that there are not enough people.

There are not enough project managers, and it is very difficult to do it just by relying on him, Jia Yiming and a few old men in the base.

"This time I want lithium-aluminum alloy, a high-strength lithium-aluminum alloy, which requires at least advanced than foreign countries. Use this to be the main material of our helicopter!" Liu Yijiu said without hesitation.

After Liu Yijiu said this, he directly handed the stack of materials written in Xiuli text to Jia Yiming, "This is some information, which contains various material formulas. The preparation process abandons the ingot metallurgy method commonly used abroad and at home, and uses our experienced powder metallurgy. After all, the mass ratio of lithium elements in the lithium aluminum alloy obtained by the ingot metallurgy method is difficult to exceed three percent, which is not beneficial to high-strength and light-weight alloy aluminum..."

He did not explain the source of the information given by Liu Yijiu. After all, he used to say that these information were obtained by Liu Suzhi's original layout in foreign technology spies.

The people in the base agree with this kind of thing, because many people returned to China with Liu Suzhi, and the main management cadres and technical personnel were Liu Suzhi's people.

"Powder metallurgy is also used abroad now? This information is very complete. We only need to produce it according to this preparation process and production formula. Just conduct performance testing..." When we saw the material production process in Liu Yijiu's hands, Jia Yiming's eyes shone.

Especially when I saw that there were detailed elemental formulas, although the preparation process was not accurate to every step, it also gave a rough range. Such data is really beneficial to their research.

"Yes." Liu Yijiu smiled bitterly in her heart and nodded quietly on her face.

"There are also rare earth elements added here? Director Liu, this..." When I saw the detailed formula and asked to add rare earth elements, I was immediately surprised.

Rare earth elements, the international research should be the top field.

After Liu Yijiu's reminder, the materials they studied were constantly added with trace amounts of rare earth elements, which promoted the performance of the entire material very significantly.

The most obvious thing is the gun steel of their new tank gun of Longwei type, which uses a large amount of rare earth elements.

"According to the research of some top foreign laboratories, rare earth elements are essential. Cerium elements can effectively reduce the impact of impurities such as fe, private, na, k on plasticity and fracture toughness, and improve performance; at the same time, segregation at grain boundaries can inhibit the depletion of solutes such as lithium elements near grain boundaries and improve fatigue strength..." Liu Yijiu told the role of rare earth elements in this alloy without thinking.

For him, he is not a strong point, and he is also not very powerful in the engine power system.

And the materials are his strengths.

Lightweight and high-strength materials are the direction of his research.

Add different rare earth elements into various alloys, which are high-performance materials they often use.

Lithium-aluminum alloy. After Germany developed the first lithium-containing aluminum alloy sleron in 1924, the Soviet Union and the United States also strengthened their research on this. It was not until the late 1980s that the two countries developed a complete lithium-aluminum alloy system, but the addition of rare earth elements did not start until the 1990s.

If Liu Yijiu wants to change the situation of domestic military industry and protect domestic rare earth resources, avoid being plundered by foreign countries and let his grandsons randomly sell these rare raw materials that are not many in the world, he can only open his own gold fingers and make rare earths as soon as possible, which basically has no research on domestic strategic resources related to high-end and cutting-edge fields such as electronics, top military industry and computer fields, and so on, let national tycoons pay great attention to it.

Such resources must not be opened to the private sector.

Otherwise, in the end, in his era, many rare earth resources in the Republic had to be purchased from abroad!

This is the sorrow of the entire Republic.

The sadness caused by ignorance.

"So, rare earth elements are really omnipotent? Whether it is special steel, high-temperature alloys, or even aluminum alloys, they can be used?" Jia Yiming was a little shocked.

He had never expected that the rich rare earth resources in China played such an important role.

Rare earth elements are not used in various materials, but the improvement of material performance is too significant.

Liu Yijiu nodded, "Jia Gong, we have also used a lot of rare earth elements, and you have also learned a lot of the properties of these rare earth elements. In the next step, our purpose is to coordinate the establishment of a rare earth element performance research project team..."

It is necessary to specialize in the performance of rare earth elements.

In Liu Yijiu's era, he did not have a thorough study of rare earths.

Although countries around the world have invested a lot of energy in the research of these elements after the 1990s, they have no way to fully understand them.

"I won't mention this for now. If there are no achievements, it will not be an easy task to convince the central leaders. Now, both Japan and the United States are hoping that China will expand the export of rare earth resources. These rare earth elements have a very high effect on the electronics industry. So, I need results!" Liu Yijiu himself could have directly taken out the performance and effect report of the rare earth elements.

However, this is really too criticized.

There is no research, just theoretical research, the data obtained cannot be convincing. Without data, it cannot be convincing.

"Or what if I can do this experiment after I finish the work in my hand?" Jia Yiming had a headache.

I was worried that Liu Yijiu would take this opportunity to set up a research team for rare earth elements.

Zone 2 was originally a material technology reserve area. The number of people was the smallest in the entire base. Of course, there were also a lot less than Zone 9 that produced and studied ammunition. After all, there was no need to produce it in the past.

"No, this matter must be started now." Liu Yijiu shook his head firmly.

This technology must be used to get funds from the aerospace system.

As long as it is researched, the performance of aerospace aluminum materials used now will be much better than that used by aerospace. Don’t worry about aerospace not spending a lot of money to buy technology from them.

In terms of aerospace, research on lithium-aluminum alloys has just begun. By the time of adding rare earth elements, we have to wait until we enter the 21st century.

"What? Added projects?" Zhao Maoping naturally felt bitter when he heard Liu Yijiu say that he asked them to cooperate in the research of new high-strength aluminum alloys.

He is inspecting the work in the workshop. At present, Liu Yijiu's meaning is to try to develop towards the preparation process of powder metallurgy as much as possible, and to carry out some research on chemical preparation processes. The traditional melt preparation process has been reduced.

The entire country is studying these traditional production processes, so they naturally do not need to invest too much in this regard.

"We lack people, but you don't know..." Zhao Maoping was very upset.

There are many people in District 2, but there are too many projects.

Materials are the basis, limiting the development of all technologies.

"Don't worry, we can borrow people from other units in this regard. You can borrow people from our neighbor's house next door..." Liu Yijiu said with a smile.

There are many people in the field of materials research in the next door.

Many people are researchers in high-temperature alloys and aluminum materials.

"Isn't that good? We borrowed a lot of people from aerospace in the past two years, and they have been urging us to return them. It's impossible to borrow them again!" No matter which unit it is, when we hear that the Ninth Hospital borrows people, we will definitely say no to them.

Especially Factory 298, 50 or 60 people were lent by the Ninth Hospital in the past two years, but those who went there to borrow were under the guise of the third-level department, which was the Aerospace 002 Base next door.

Last year, Factory 298 had already reported it and went directly to the third-level department. The Ninth Institute never admitted this matter.

The 002 base was even more furious and wanted to find out the person who framed them, but I didn't know that it was their neighbors who were doing it.

"What's the matter? We are all neighbors. There are many people in them. It's not a big deal for us to borrow a few, right? If it really doesn't work, just use the aluminum alloy technology we are studying now to exchange it with them." Liu Yijiu smiled.

He is not worried that these units will not be given to others.

In the past, he was thinking about making money by making money. Now that people have changed, they can't do everything together for some things. At that time, they can completely control half of China's top industry, which will make the big guys very afraid.

The 002 base has an aluminum alloy production factory, but its performance is not very good, and even some top rocket shells are relatively barely used.

If we had the most high-strength lightweight aluminum alloys from the United States and the Soviet Union, we would naturally be able to replace them.

At that time, the materials factory at the 002 base would help them make money.

"What will they do?"

"There is no harm in trying it, right? As long as you get through the past two years, it won't take too long. By next year, we will be able to get a batch of materials majors from various schools..." Liu Yijiu didn't dare to guarantee it.

They have made great efforts to get their neighbors.

Liu Yijiu didn't dare to go to the aerospace base. As long as he went there, he could think of some things he did. Cao Zhijiang was the first person he borrowed from the aerospace.

Hangtian realized that something was wrong and asked Xie Heping many times, and wanted to take Cao Zhijiang back, but he couldn't find Xie Heping.

Liu Yijiu is very clear.

When he told the people from the management committee about this matter, it aroused the doubts of many old men.

They were speechless about Liu Yijiu's emphasis on the role of rare earths.

A strange research system requires more manpower and energy.

"Xiao Liu, although this rare earth element has greatly improved the performance of our cannon steel, and even high-temperature alloys are very effective, but is this really so outrageous as you said?" Everyone knew about the materials. Yin Xianping, director of the Fourth District, asked with a frown.

They are in charge of electronic research, computer chips and other things, and missile guidance is also their business. Of course, the seventh district in radio also share some of the projects.

Since Liu Yijiu took charge, the base began to use rare earth resources in almost all materials, including radio, chips, and missile guidance. There is no reasonable understanding of rare earths in China.

They don't believe that this material can be so terrifying.

"This is not outrageous, but it is too outrageous!" Zhao Maoping said with a wry smile.

They never thought that a basic elemental material could involve a series of fields such as machinery, metallurgy, electronics, chips, semiconductors and even medicine.

"What's this awesome? There is a more amazing material in our base! It's just that there is no larger-scale research on the issue of technical strength and capital..." Liu Suxue deeply despised these guys.

"There is another kind of more amazing thing? Lao Liu, I don't study much as you, don't fool me..." Zhao Maoping was the first to disbelief.

"Hmph, the graphene in our base is far more amazing than this!" Liu Suxue said coldly.

The people in the base have far less understanding of epoch-making things like graphene.

This is the top secret material in the base. The only people who come into contact with them, the only ones they are studying, and everyone is still in the cave next to them!

"Okay, whether rare earths have such powerful performance and effects, such amazing performance and effects, is useless to discuss here. Only by investing more and studying more can we be clear!" Liu Yijiu was speechless. These guys only looked at the results and believed what they saw.

It is completely unnecessary to discuss the role of rare earth elements here.
