Liu Yijiu ignored Wang Shunyi, and did not continue to talk about the underground base below.

Zheng Hao shouldn't know about the research room in that place.

The people in there have never seen it above, and Liu Yijiu doesn't know their specific situation, and he doesn't know what projects he is studying. But at a glance, it really has something to do with nuclear technology, and this kind of thing is top secret, and it's best not to get involved.

"Okay, I'll go to the Ninth District first to see the situation, and I don't know if the tail stabilized armor-piercing shell they got has come out......" Liu Yijiu didn't plan to continue talking about this matter. Wang Shunyi doesn't know much about this, and Zheng Hao doesn't understand it at all.

It is estimated that he has not been to the ninth district much.

"It's also in vain to research it, why don't there be tanks here. In addition, this armor-piercing bullet is not as easy to get as imagined, you better go to the material side to have a look, and don't you let them get some new materials in the second area? Without materials, everything is for nothing! Wang Shunyi said to Yun Fei.

Jia Yiming is in the second district, and although he is still under surveillance, he has obviously become the chief engineer of the superalloy project over there.

As for the person in charge of the second district, Liu Yijiu knew that it was Zhao Maoping, who was in charge of materials in the third district, and after the base returned to normal, some of the management personnel and technical personnel who had been delegated returned to their posts.

Otherwise, Zhao Maoping would not have been bored to see what Liu Yijiu wanted to do.

Aerospace aluminum. This is the shortcoming of the republic, and this material is in great demand for aerospace materials.

"I'm going to have to go over and take a look at the materials. I don't know if Mr. Jia has brought out our new type of cannon steel, but that's what I took out of the Americans......" Liu Yijiu is lying now, but he came out of his mouth.

"I think you should go back and rest, you're already a family now......" Zheng Hao said with a sinister expression.

Just now, these two guys used professional skills to destroy him, and he felt that he should take revenge.

Lao Wang, he has no choice, but Liu Yijiu is different.

"I have a family of. I've never heard of beating mandarin ducks, but I've never heard of such a thing......," Liu Yijiu suddenly rolled his eyes. Didn't say anything at all, and walked away quickly.

From after they returned to the base. I don't know what's going on, I directly dialed a room for him in the base, and then got a big red new quilt and new sheets or something, Li Rui didn't refuse at all. I just moved there.

Under the instruction of Zheng Hao and Xie Heping, a group of aunts directly moved Liu Yijiu's things to the new house. Originally, it was said that when preparing for the New Year, the cafeteria would add food and drink the wedding wine together, so the two of them were married.

This Comrade Liu Yijiu is very scorched, and since then, he has been hiding here and never going out at all.

In the revolution & life marriage, there are many marriages in the line of fire, but this should not have anything to do with him Liu Yijiu.

For such a thing, anyone, will be disgusted. What's more, he clearly knew that Li Rui was a spy arranged by the above to spy on him here, which was even more unacceptable.

No one can stand such a thing.

"Xiao Liu, in the old days. It's not a few things to mess with the mandarin duck spectrum, and most people can't even see what the object looks like before they get married. You're much better than them, you've known each other for a long time before......" Zheng Hao howled at Liu Yijiu's back with a wicked face.

Liu Yijiu ignored him, quickened his pace, and soon disappeared into the passage.

"If you want to blame, you can only blame Lao Li for being too anxious to let her daughter go to the battlefield. Nothing ......," Wang Shunyi sighed.

Liu Yijiu's thoughts, how could he not know?

No one wants to fall asleep next to him, a female spy who specializes in spying on him.

"Aren't you worried that your son-in-law will be snatched away by the Situ family......" Zheng Hao still had a smile on his face.

Ignored the words of the latter two. Liu Yijiu took several deep breaths before calming down the anger in his heart. He had no choice but to resist with silence.

Zone 2 is also in a valley. The site of the Nine Courtyards base must have wasted a lot of effort at the beginning, a low mountain peak in the middle, surrounded by nine valleys, from the middle of the low mountain peak to the outside stretched out ten ridges, and it was relatively regular.

If you look at it from the sky, you have to sigh at the magic of nature, as if it was specially prepared for the existence of the Ninth Academy, and the surrounding nine valleys are exactly nine subdivisions, and in the middle is the headquarters of the Ninth Academy......

The second area is the area with the most factories and the least number of people in the entire base. There aren't many operators here, and most of them are technicians. There are too many types of materials, and even in this, the backup technology equipment is not the most complete.

It's just some very important, very critical technologies that are there.

These equipment and other things were imported from abroad. Many of them cannot be produced domestically, high-frequency furnaces from Russia, vacuum furnaces from East Germany, high-temperature furnaces from Switzerland, smelting furnaces from Ukraine...... The area of these equipment is not very large, after all, they are small furnaces for experiments, and at the same time, they are also equipment for small-scale production of materials used in the base.

In the fifties, like high-frequency furnaces and vacuum furnaces, these were top-notch equipment, and I don't know how the state got them, but now, these furnaces are not working. Many alloys need to increase the temperature to more than 2000 °C, such as some alloy materials in powder metallurgy, such as various tool materials, there is no way to melt the metal, and these materials can only be sintered together at high temperature and high pressure by powder metallurgy......

Tungsten, which is used most in weapons and equipment to increase the strength of materials, has a melting point of up to 3410 °C, and molybdenum, which is also used a lot to increase the toughness of materials, has a melting point of 2610 °C. There are other metal elements that play a very important role in the strength and performance of weapons and equipment, and the melting point is also very high, and it is impossible to achieve it if you want to use the smelting manufacturing process.

Liu Yijiu is also helpless about these.

There are more advanced equipment, and the technical conditions of this era cannot be manufactured at all!

After entering the second area, I greeted many technicians wearing white coats and walked inside. On the material side, there are many workshops, these workshops are not large, but basically each workshop will have a key material manufacturing technology and related equipment.

Jia Yiming has been researching superalloys from the beginning, and after entering here, he is still a superalloy. Due to the high strength requirements and harsh working conditions, this superalloy is composed of some high-temperature resistant metal alloy elements, which are the key materials used in the manufacture of aerospace engines.

"Xiao Liu, are you here?" As soon as Liu Yijiu walked outside the building of the Second District Management Center, he saw Zhao Maoping rushing out, that is, the old man Zhao who scared him at the beginning.

"Uncle Zhao, what are you doing in a hurry? I'll come over to take a look at the situation, and now many projects are waiting for the progress of the research here......" Liu Yijiu said hello and said very helplessly.

Material is the key.

"Then you came just in time, the formula you provided, after various analysis experiments, proved that the strength of the material is indeed very high, but now there is a problem, the various components in it are very uneven, and there are more impurities in it, which affects the performance of the material......" Zhao Maoping took Liu Yijiu to the workshop while introducing the situation.

Liu Yijiu immediately frowned.

He's provided a lot of recipes for the ingredients.

I don't know which recipe is the problem.

"What kind of material?"

"Tungsten alloy steel with rare earth elements and the kind of cannon steel process formula you provided......"

"Has tungsten alloy steel been tested for the purity of tungsten powder? Is the holding time based on the data I provided? In addition, is the formula of cannon steel remelted in an electroslag furnace? Liu Yijiu spit out a series of questions.

"The purity of tungsten alloy steel has reached 99.985%, the purity of molybdenum has also reached 99.976%, and other elements have been purified after arriving at the base......

"It's not pure enough. The purity of tungsten powder must reach 99.998%, molybdenum must also have such purity, as well as the physical state of the powder, must be passed out with a sieve of 200 meshes, and the fine powder is used to mix and evenly add vanadium These elements...... "Liu Yijiu immediately found the key point.

The purity of various raw materials is not enough, and when high-temperature sintering is carried out at the last moment, there is naturally no way to ensure that the sintered materials can have high purity, and too many impurities will eventually produce more pores inside the material, thus affecting the performance of the overall material.

"Such a high level of purity? There is no way to experiment in the short term...... "Zhao Maoping is also an expert in this area, and it is too difficult to reach the thousandth place, such purity.

"Uncle Zhao, this can't have any kind of idea, even if there is no way to come up with it in a short period of time, we must study this aspect. Materials are all the key issues that restrict our development. If they can't be used, or if the results are not good at all, the research results are basically useless, and a lot of money is wasted. Now you also know the situation of our base, there is no money, and we can't afford to waste it......" Liu Yijiu gritted his teeth and said.

He knew that being able to achieve such purity was already the limit.

This is the best degree of craftsmanship that he provides.

But this kind of purity, no, many rare elements in these materials are only added to the thousandths or even thousandths of rare elements in the end to change the overall performance. (To be continued)

ps: Today's state is much better, Hulu will try to code as many words as possible, but I still can't guarantee how many there will be today!
