During the Spring Festival, Liu Yijiu only rested for a few days, although most of the time he was in a drunken state or on the way to a drunken state, but the technicians and managers who were transferred to tackle the turboshaft engine were still focused on their work.

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

At present, there has been no progress in the helicopter, which means that preparations have been underway.

Although it is said to be the stage of program demonstration, the plan is basically the use of Z-7 and Mi-24 schemes, and there will not be too many problems.

The problem is all kinds of underlying data.

"And to develop a new type of aluminum alloy? Director Liu, there is no mistake, right? We already have an advanced aluminum alloy for aerospace. For Liu Yijiu's project to develop a new type of aluminum alloy as the base codenamed Z-91 general helicopter transformation, Jia Yiming did not get the task a few years ago, but he did not expect that after the Spring Festival, Liu Yijiu asked him to start this matter.

He is now working on the improvement project of titanium alloys and nickel-based superalloys, which has reached a critical stage.

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 rely on him and a few old men in the base.

"This time I want lithium aluminum alloy, high-strength lithium aluminum alloy, which is at least more advanced than foreign ones, and use this as the main material of our helicopter!" Liu Yijiu said without hesitation.

After Liu Yijiu said this, he directly handed over a stack of materials written in beautiful characters in his hand to Jia Yiming, "This is some information." There are various material formulas in it, and the preparation process abandons the ingot metallurgy method commonly used in foreign and domestic countries, and adopts our experienced powder metallurgy, after all, the mass ratio of lithium elements in the lithium-aluminum alloy obtained by the ingot metallurgical method is difficult to exceed three percent, which is of high strength. There is no benefit to the lightweight alloy aluminum......"

He didn't explain the source of the information given by Liu Yijiu, after all, he used to say that these materials were obtained through Liu Suzhi's original layout of foreign scientific and technological spies.

For such a thing, the people in the base deeply agreed, because many people followed Liu Suzhi back to China, and the main management cadres and technicians were Liu Suzhi's people.

"Foreign countries are also using powder metallurgy methods now? This information is very complete, we only need to produce it according to this preparation process and production formula, and conduct performance tests......" From the time he saw the material production process in Liu Yijiu's hands, Jia Yiming's eyes lit up.

Especially when you see that there is a detailed elemental recipe inside. Although the preparation process is not accurate to each step, an approximate range is given, which is really beneficial for their research.

"Hmm." Liu Yijiu smiled bitterly in his heart, and nodded quietly on his face.

"Rare earth elements are added to this? Director Liu, this ...... "When I see the detailed formula, I also ask to add rare earth elements. I was immediately surprised.

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

They study the material. After Liu Yijiu's reminder, the continuous addition of some trace amounts of rare earth elements has a very obvious promotion of the performance of the entire material.

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

"According to the research of some top laboratories abroad, rare earth elements are essential. Cerium can effectively reduce the influence of Fe, Si, Na, K and other impurities on plasticity and fracture toughness, and improve performance. Meantime. In grain boundary segregation, it can inhibit the dilution of solutes such as lithium near the grain boundary and improve the fatigue strength...... "Liu Yijiu didn't want to say the role of rare earth elements in this alloy without thinking about it.

Engaging in aircraft design is not his strong point. The power system of the engine is also not very powerful.

And material, that's his forte.

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

Different rare earth elements are added to various alloys, which are high-performance materials that they often use.

Lithium aluminum alloy, from 1924 Germany developed the first lithium element of aluminum alloy Scleron, the Soviet Union and the United States also strengthened the research in this area, until the end of the eighties, the two countries developed a perfect lithium aluminum alloy system, but the addition of rare earth elements, until the nineties began to start.

If Liu Yijiu wants to change the situation of the domestic military industry, and protect the domestic rare earth resources, avoid being plundered cheaply by foreign countries and let those domestic grandsons sell these rare raw materials that are not much in the world, he can only open his own golden finger and make rare earths, which are basically not studied in China, as soon as possible to make the national bigwigs attach great importance to the strategic resources in high-precision and cutting-edge fields such as electronics, top military industry and computer fields.

This kind of resource must not be open to the private sector.

Otherwise, in the end, that is, in his time, many rare earth resources in the Republic have to be purchased from abroad!

This is the sorrow of the whole republic.

Because of the sorrow caused by ignorance.

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

He did not expect that the country's rich rare earth resources would have such an important role.

Rare earth elements are not used too much in various materials, but the improvement of material properties 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 about the properties of these rare earth elements." In the next step, our goal is to coordinate the establishment of a rare earth element performance research project team......"

Specializing in the properties of rare earth elements, this is a must.

In Liu Yijiu's time, rare earths were not fully studied.

Countries around the world, although they have invested a lot of energy in the study of these elements since the 90s, have not been able to fully understand them.

"Let's not mention this for now. If there are no grades. It is not easy to convince the head of the central government, and now both Japan and the United States are hoping that China will expand the export of rare earth resources, which have a very high role in the electronics industry. So. I need results! Liu Yijiu himself could have directly come up with a report on the performance of rare earth elements.

It's just that this is too criticized.

There is no research, only theoretical research, and the data produced are not convincing. And without data, it is unconvincing.

"Why don't you wait until I'm done with my work?" Jia Yiming had a headache.

I am worried that Liu Yijiu will directly take this opportunity to set up a rare earth element research team.

The second area was originally a material technology reserve area, and the number of people was the smallest in the entire base, of course. Compared with the ninth area, which produces and researches ammunition, it is also a lot less, after all, there was no need to produce it before.

"No, this must be done now." Liu Yijiu shook his head resolutely.

This technology has to be used to get money from the space system.

As long as it is researched, the performance will be much better than that of the aviation aluminum used in aerospace, and there is no need to worry about aerospace not spending a lot of money to buy technology from them.

In aerospace, research on lithium-aluminum alloys. Now it's just getting started, to adding rare earth elements. We have to wait until the 21st century.

"What? Another project? When Zhao Maoping heard Liu Yijiu say that he asked them to cooperate with the research of a new type of high-strength aluminum alloy, he naturally made a bitter face.

He is inspecting the work in the workshop, and Liu Yijiu is currently trying to develop the preparation process of powder metallurgy as much as possible, as well as to carry out some research on the chemical preparation process, and the research on the traditional melting preparation process has been reduced.

The whole country is working on these traditional production processes, so naturally there is no need for them to invest too much in this area.

"We're short of people. It's not that you don't know......" Zhao Maoping was very distressed.

There are a lot of people in the second district, but there are too many projects.

Materials are the basis and limit 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.

Next door to aerospace has a lot of people in the field of materials research.

Many people are researchers in the field of superalloys and aluminum.

"Isn't that okay? We borrowed a lot of people from aerospace in the past two years. They have been urging us to pay it back, and it is impossible to borrow it again! "No matter which unit it is, as soon as you hear that the Ninth Academy has borrowed someone, you will definitely say no to them.

In particular, the 298 factory has been loaned fifty or sixty people by the Ninth Academy in the past two years, but the people who went there to borrow people were all under the guise of the third-level department, which was the aerospace 002 base next door.

Last year, the 298 factory had already reported it, and it was directly in the third-level department, and the Ninth Academy never admitted it.

The 002 base is even more furious to find out the person who planted them, and they don't know that it is their neighbor's ghost.

"What's this, we're all neighbors, there are a lot of them, let's borrow a few, it's nothing, isn't it? If it really doesn't work, we can exchange them with the aluminum alloy technology we are researching now. Liu Yijiu smiled.

He wasn't worried about the units not being given to them.

In the past, he was thinking about the white wolf with empty gloves, but now that people have changed, there are things, they can't do everything alone, and when the time comes, they will be able to control half of China's top industry, which will make the bigwigs very jealous.

The 002 base has an aluminum alloy production plant, but the performance is not good, and even some top-level rocket shells are barely used.

If there is the top high-strength lightweight aluminum alloy of the US imperialists and the Soviet Union, it is natural that they can be replaced from them.

At that time, let the material factory of the 002 base help them make money.

"Will they do it?"

"There's no harm in trying, right? As long as we get through these two years, it won't even take too long, and wait until next year, we will be able to get a group of students majoring in materials from various schools to come over......" Liu Yijiu didn't dare to guarantee.

They take their neighbors to a bad place.

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

Aerospace realized that something was wrong, and asked Xie Heping many times, wanting to go back to Cao Zhijiang, but he couldn't find Xie Heping.

Liu Yijiu is very clear.

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

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

An unfamiliar research system that requires more manpower and energy.

"Xiao Liu, although this rare earth element has greatly improved the performance of our cannon steel, even the superalloy is very effective, but this is really as outrageous as you said?" Everyone understands the material. Yin Xianping, director of the fourth district, asked with a frown.

They are in charge of electronic research, computer chips and the like are now handed over to them, missile guidance is also their business, and of course, the seventh region of radio has also shared part of the project.

Since Liu Yijiu was in charge of the base, almost all materials, including radios, chips, and missile guidance, have begun to use rare earth resources, and China has not had a reasonable understanding of rare earths at all.

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

"It's not outrageous, it's too rebellious!" 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 kind of rebellion is this? There's an even more anti-heaven material in our base! It's just that at present, because of the technical strength and financial problems, no larger-scale research has been carried out......" Liu Suxue deeply despises these guys.

"Is there a more rebellious one? Lao Liu, I don't read as much as you, don't fool me......" Zhao Maoping was the first to disbelieve it.

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

The people in the base have far less understanding of such an epoch-making thing as graphene.

This is the top-secret material in the base, and the people who come into contact with it, only them, are still in the cave next to them, and everyone is still in the cave next to them!

"Okay, whether the rare earth is so powerful, such a performance and effect against the sky, it is useless for us to discuss here, only with more investment and more research, we can be clear!" Liu Yijiu was speechless, these guys only look at the results and only believe what they see.

Now discussing the role of rare earth elements here is completely unnecessary.

Rare earths limit the development of the world's top and most cutting-edge science and technology! (To be continued......)
