Super military empire

During the Spring Festival, Liu Yijiu only took a few days off. Although most of the time he was in a drunk state or on his way to a drunk state, the technicians and management personnel who were transferred to the turboshaft engine still had energy. It is at work.

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

There has been no progress in helicopters, which is equivalent to making preparations all the time.

Although it is the demonstration stage of the scheme, the scheme basically adopts the straight -7 and the Mi-24 scheme, which will not cause too many problems.

The problem is all kinds of basic data.

"A new type of aluminum alloy is going to be developed again? Director Liu, are you not mistaken? We already have an advanced aluminum alloy for aerospace." For Liu Yijiu, the base code for the development of a new type of aluminum alloy is the Zhi-91 general purpose helicopter. Jia Yiming didn't get the task for the renovation of the supporting project, but he didn't expect that after the Spring Festival, Liu Yijiu would ask him to start this.

He is currently working on improvement projects for titanium alloys and nickel-based superalloys, and has now 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 supervisors either. It is very difficult to do it just relying on him, Jia Yiming and a few old men in the base.

"This time I want lithium aluminum alloy, high-strength lithium aluminum alloy, which is at least advanced than foreign ones. Use this as 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 beautiful text to Jia Yiming, "These are some materials, and there are various material formulas in them. The preparation process is abandoning foreign and domestic commonly used materials. The ingot metallurgy method uses our experienced powder metallurgy. After all, the mass ratio of lithium in the lithium aluminum alloy obtained by the ingot metallurgy method is difficult to exceed 3%, which is not suitable for high-strength, light-weight aluminum alloys. What good..."

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

The people in the base deeply agree with this kind of thing, because many people have returned to China with Liu Suzhi, and the main management cadres and technicians are all Liu Suzhi's people.

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

Especially seeing that there are detailed element formulas, although the preparation process is not accurate to every step, it also gives an approximate range. Such information is really very beneficial for their research.

"Yeah." Liu Yijiu smiled bitterly, and nodded calmly.

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

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

The materials they studied, after Liu Yijiu’s reminder, continued to add some traces of rare earth elements, which greatly improved the performance of the entire material.

The most obvious is the gun steel of their new Longweiyi tank gun, which uses a lot of rare earth elements.

"According to the research of some top foreign laboratories, rare earth elements are indispensable. Cerium can effectively reduce the impact of impurities such as Fe, Si, Na, K on plasticity and fracture toughness, and improve performance; at the same time, segregation at grain boundaries, It can inhibit the depletion of solutes such as lithium elements near the grain boundary and improve the fatigue strength..." Liu Yijiu explained the role of rare earth elements in this alloy without even thinking about it.

Engaging in aircraft design is not a strong point for him. Engaging in engine power systems is also not very powerful.

And materials, this is his strength.

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

Adding different rare earth elements to various alloys is a high-performance material they often use.

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

If Liu Yijiu wants to change the situation of the domestic military industry, and protect the domestic rare earth resources, avoid being looted cheaply by foreign countries and let those domestic grandchildren bargain and sell these rare raw materials, which are rare in the world, he can only open his own golden fingers and let him as soon as possible. Rare earth, which basically has no domestic research related to electronics, has strategic resources in high-precision and cutting-edge fields such as top military industry and computer fields, which has attracted the attention of national leaders.

This kind of resource is definitely not open to the private sector.

Otherwise, at the end of his time, many rare earth resources of the Republic have to be purchased from abroad!

This is the sadness of the entire Republic.

The sorrow caused by ignorance.

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

He never thought that the rich rare earth resources in the country played such an important role.

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

Liu Yijiu nodded, "Jia Gong, we have used a lot of rare earth elements, and you have already understood many of 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……"

It is necessary to study the properties of rare earth elements.

In Liu Yijiu's era, there was no thorough study of rare earths.

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

"I won't mention this for now. If there is no success, it will not be easy to convince the head of the central government. Now both Japan and the United States are hoping that China will expand the export of rare earth resources. These rare earth elements are important for the electronics industry. Very high effect. So, I need results!" Liu Yijiu could have directly produced a report on the performance of rare earth elements.

It's just that, this way, it is too much criticized.

There is no research, just theoretical research, and the data obtained is not convincing.And without data, it is not convincing.

"Why don't I do this experiment after I finish the work in my hands?" Jia Yiming has a headache.

I am worried that Liu Yijiu will directly use 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 nine areas that produced research ammunition, it was also a lot less. After all, there was no need for production before.

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

This technology has to be used to obtain funds from the aerospace system.

As long as it is researched out, the performance will be much better than that of the aerospace aluminum currently used in aerospace. Don't worry about the aerospace not spending big prices to buy technology from them.

In aerospace, research on lithium-aluminum alloys has just begun, and the addition of rare earth elements has to wait until the 21st century.

"What? Another project?" Zhao Maoping heard Liu Yijiu's request that they cooperate in the research of a new type of high-strength aluminum alloy.

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

The whole country is studying these traditional production techniques, and they naturally do not need to invest too much in this area.

"We are short of people, you don't know..." Zhao Maoping was very distressed.

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

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

"Don't worry, we can borrow from other units in this respect. You can borrow 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 space next door.

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

"Is this not good? We borrowed a lot of people from aerospace in the previous two years. They have been urging us to return people. It is impossible to borrow them again!" Would say no to them.

Especially for Factory 298, the Ninth Institute has loaned No. 50 or 60 people in the past two years, but the people who went there to borrow were all under the guise of the third-level department, which is the Aerospace 002 base next door.

Last year, the 298 factory had already reported it, and it was directly involved in the third-level ministry. The Ninth Academy has never admitted this matter.

The 002 base is even more furious and wants to find out the people who planted them, without knowing that it was their neighbors.

"What's the matter? We are all neighbors in the neighborhood. They have a lot of people. Let's borrow a few. It's not a big deal? If it doesn't work, we will use the aluminum alloy technology we are studying now to exchange with them." Liu Yijiu said with a face. Smile.

He doesn't worry that these units will not give people.

In the past, what he considered was the empty glove white wolf. Now people have changed, and some things, they can’t do everything at the same time. At that time, they will be able to control half of China’s top industries, which will make the big brothers. They are very jealous.

The 002 base has an aluminum alloy production factory, but the performance is not good, even some top rocket shells are relatively reluctant to use.

If there are the top high-strength lightweight aluminum alloys from the U.S. and the Soviet Union, they can naturally be replaced.

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

"What will they do?"

"There is no harm in trying, right? As long as the past two years pass, or even not too long, until next year, we will be able to get a group of students majoring in materials from various schools..." Liu Yijiu could not guarantee.

They pit their neighbors not lightly.

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

Aerospace realized that it was wrong, and asked Xie Heping many times. It wanted to send Cao Zhijiang back, but couldn't find Xie Heping.

Liu Yijiu is very clear.

When he told the management committee about this matter, it caused many old men to question it.

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

An unfamiliar research system requires more manpower and energy.

"Little Liu, although this rare earth element has greatly improved the performance of our gun steel, even high-temperature alloys are also very effective, but is this really outrageous as you said?" Everyone knows about materials. .Four District Director Yin Xianping frowned and asked.

They are in charge of electronic research. Computer chips and the like are now handed over to them. Missile guidance is also their business. Of course, the seven districts of radio control also share part of the project.

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

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

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

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

"Why is this sky-defying? There is a more sky-defying material in our base! It's just that there is no more large-scale research due to technical strength and funding issues..." Liu Suxue deeply despised these guys.

"There is another kind that is more against the sky? Old Liu, I don't have as many studies as you, don't fool me..." Zhao Maoping was the first to not believe it.

"Huh, the graphene in our base is far more against the sky than this!" Liu Suxue said coldly.

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

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

"Okay, whether the rare earth thing has such powerful and anti-sky performance and effect, we are not using it to discuss here, only more investment and more research can make it clear!" Liu Yijiu was speechless, these guys only looked at the results. , Only believe what they see.

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

Rare earths restrict the development of the world's top and most cutting-edge technology!
