In the military industry that year, the cloud bombs started to wash the ground for monkeys

"Old Jia..." Wei Xingshan blushed and shouted.

Because he saw that the haze on Jia Yiming's face had dissipated.

His mental state looks much better than ever.

"Leaders, Mr. Jia is willing to join the 618 base, and he is ready to work at any time." Lu Xuan said calmly.

"Really...really?"

Wei Xingshan had already seen it from Jia Yiming's mental state.

But hearing Lu Xuan say this, it was still difficult to conceal the excitement in his heart.

Wang Mingyi wanted to say something, but he only felt something stuck in his chest, and he couldn't say anything.

He didn't know how Lu Xuan persuaded Jia Yiming to come out of the mountain again, but it didn't matter anymore.

"Old Jia, you haven't lost your major these years..."

Yang Changgen knew it was inappropriate to ask this sentence.

But as the top leader of the base, there are some things I have to say.

"Although I haven't been engaged in research work in this area these years, can some things be thrown away if you want to?"

"At the beginning, when the country was most difficult, we were sent to East Germany to study. The cost of studying abroad is so high, how can we just throw it away?"

"Don't worry, although I don't have the conditions to do experiments these years, I have continued to study many theoretical things. Here are some materials I have studied over the years."

"There are a lot of things in it that need to be verified by experiments, especially the improvement plan for the superalloy powder smelting process and formula. You can use it for verification first."

"My political review work will take a long time. In terms of experiments, I can only leave it to you. When the political review work is over, it will also allow me to take over without having to start from scratch."

Jia Yiming's expression was calm, and he didn't seem to have any complaints about the unfair treatment these years.

It's not that he really became a saint, but that their generation was to serve the country from the beginning.

It's just that the country has taken a detour, and they can't help it.

He believes that the country will return their innocence one day.

Those who engage in the defense industry believe in their own country at all times.

This is the reason why they have dedicated their lives to the country, and it is also the most admirable group of people.

"Great, as long as the material is okay, our gun steel project should progress faster..."

Wei Xingshan took the material written by Jia Yiming with trembling hands, and two lines of old tears fell down.

Jia Yiming nodded, without saying too much, turned and went back into the room.

After closing the door, I heard two shouts of "Dad" coming from the room.

Jia Yiming has a son and a daughter, who were also picked up by Wei Xingshan.

All three members of the family were arranged at the base, which was regarded as a family reunion.

Lu Xuan let out a long breath of relief.

Although he comes from a later generation and has advanced military industry theory and knowledge, it is impossible to cover everything.

In terms of basic materials, it is the top priority of the defense industry. With Jia Yiming's help, many detours will be avoided.

a conference room.

After sorting out the materials and distributing them to the leaders and experts present, Lu Xuan said:

"This is some actual measurement data of the 336 rocket launcher and the Red Arrow individual rocket launcher I obtained on the front line. Let's take a look."

"The accuracy of the 336 rocket launcher needs to be improved, which requires a microcomputer to perform calculation corrections, and Cao Zhijiang's computer research team is responsible for this."

"In addition, the armor-piercing capability of the Red Arrow individual rocket launcher needs to be improved. It cannot penetrate the front armor of T64 and T72 tanks. This requires us to increase the power of the warhead."

When Director Yang heard this, he felt a pain in his heart: "That is to say, we have to get more powerful ammunition?"

Ammunition is a huge hole, and no matter how much money is filled in, there may be no results.

Lu Xuan nodded: "The ammunition must be improved, especially armor-piercing ammunition. We can get some uranium ore that has been refined from nuclear materials."

Tail-stabilized sabot-piercing projectiles must be produced.

But for now, the best solution is to get depleted uranium bombs first.

This thing is the nemesis of the early third-generation tanks, and it is basically impossible to defend.

"Uranium 238?" Wang Mingyi asked in surprise.

Uranium 238 is left over from the extraction of uranium 235, which is not known to be useful in this age.

"It's this waste that we use to make depleted uranium alloys and then make depleted uranium armor-piercing bombs."

When Director Yang heard the words, his eyes lit up immediately: "Comrade Xiao Lu? Are we going to get individual nuclear weapons?"

Director Yang couldn't tell the difference between uranium-235 and uranium-238. He only knew that uranium was an essential raw material for making mushroom bombs.

Hearing Yang Changgen's words, all the experts present looked like I didn't know him.

"Is there something wrong?" Director Yang was a little confused.

Lu Xuan didn't mean to explain it to him. It couldn't be explained clearly in a sentence or two, but simply said:

"Depleted uranium can greatly increase the armor-piercing strength or armor resistance. After the depleted uranium bomb hits the target, it has a high-temperature burning effect of [-] degrees..."

Wang Mingyi immediately said: "How to make depleted uranium alloy, you tell me the method, and I will arrange someone to do it."

"Although the radioactivity of uranium-238 is low, it cannot be said that it is completely non-existent, so you should stop doing this."

Lu Xuan is the treasure of the base, Wang Mingyi doesn't want Lu Xuan to have any mistakes.

There is nothing else in the Rabbit House, but there is as much waste as uranium-238.

"That's okay, I'll go to the material research base to have a look." Lu Xuan did not refuse the leader's kindness.

When I came to the material research base, I greeted the technicians in white coats and walked inside.

The material research base does not have a soul leader, and ordinary technicians just have black eyes and can't do anything.

However, Jia Yiming's arrival will change everything here, so Lu Xuan intends to come to understand the situation first.

"Comrade Xiao Lu, you came at a good time. The material formula you provided has been proved to be very strong through various analysis experiments."

"But now there is another problem. The various components in it are very uneven and there are too many impurities, which seriously affect the performance of the material."

As soon as Lu Xuan entered the workshop, a material expert asked Lu Xuan to ask questions.

Lu Xuan was very speechless, even if he gave the material formula, they couldn't produce qualified materials.

Now that Jia Yiming is here, Lu Xuan will save a lot of things, otherwise many things would not be done.

Material is the foundation!

"What kind of material?"

"Tungsten-molybdenum alloy steel with rare earth elements..."

The material expert quickly said: "The purity of tungsten-molybdenum alloy steel has reached 99.8%, and your requirement is 99.9%, which is too difficult."

Lu Xuan quickly found the key point: "When tungsten and molybdenum are in the powder physical state, they must be screened with a [-]-mesh sieve, and then vanadium element is added...".

028 Before building a tank, first build a gun

The reason why Lu Xuan personally came to experiment with tungsten-molybdenum alloy steel materials was mainly to improve gun steel technology.

After returning from the southwest front, Lu Xuan realized that the Rabbit family's cannon steel technology was really not good.

Regardless of howitzers, mortars, 336 rocket launchers, Red Arrow individual rocket launchers, or tank guns, they all use old-fashioned tungsten alloy steel.

Although tungsten alloy steel has high hardness, it has excellent high temperature resistance.

But it is also because of too much hardness that the toughness of the barrel is low.

After many shots, the barrel will quickly reach the metal fatigue strength due to the high temperature and high pressure generated when the cannon is ejected.

As a result, the barrel must be replaced when it reaches the end of its useful life.

Otherwise, the bombardment hit rate will drop, and even a bombing accident will occur.

Especially the tank gun is the rabbit's shortcoming.

The barrel has to be replaced if it hits less than 300 rounds.

The bear's tank gun can fire 400 to 500 rounds.

The tank guns of Eagle Sauce, John Bull, Hans Cat and other countries can fire 500 to 600 rounds.

The Rabbit military has been aware of this problem for a long time, and it also attaches great importance to the research of artillery gun steel.

But the basic industry of the rabbit is too weak, and it is not possible to catch up with the bear or even the western countries in a short time.

Now, Jia Yiming, a material expert, will soon be able to work and help Lu Xuan improve his gun steel technology.

Therefore, Lu Xuan came to give guidance first, and when Jia Yiming came, he could directly produce a new type of gun steel.

"Rare earth elements, are they really that important?"

I can always hear Lu Xuan mentioning the importance of rare earth elements, and the experts are very puzzled.

"Of course it's important. The performance of gun steel with a small amount of rare earth elements will be greatly improved. You will know when you get the new gun steel out and test it."

Lu Xuan couldn't explain it clearly to these half-assed experts, so he had to use facts to prove it, and at the same time make the country's top leaders pay attention.

Rare earth elements are not only very important for the military industry, but also indispensable in aerospace, satellite guidance, and electronics industries, but the rabbits don't realize it at all.

Rabbit rare earth resources are the countries with the largest proven reserves and the richest types in the world.

However, it is the countries with developed industries such as Eagle Sauce, Foot Pot Chicken, and Hans Cat that have done the most research on rare earths.

After Rabbit's reform and opening up, in order to obtain more foreign exchange to develop the economy, a large amount of rare earth resources were exported at the price of pork.

Especially foot pot chicken, which is not available in China, so they desperately import it from rabbits and hoard it.

It can be said that the advanced electronic industry of the foot pot chicken is based on the cheap rare earth resources of the rabbit.

By the time Rabbit discovers the great role of rare earths, the domestic rare earth resources have been almost sold out.

This is a huge loss of rabbit resources, now that Lu Xuan is here, naturally he will not let this happen again.

Just as Lu Xuan was diving into the experiment and research of new gun steel materials, Yang Changgen came to him with a group of people.

What surprised Lu Xuan was that besides Yang Changgen, Wang Mingyi and the guard company commander Liu Dayong, there was... Zhao Min.

"Comrade Xiao Lu..."

Just as Yang Changgen was about to speak, Lu Xuan raised his hand to stop him.

Pointing to Zhao Min, he asked, "Why is she here?"

The corner of Yang Changgen's mouth twitched: "This...you should ask Company Commander Liu."

Liu Dayong blushed, and said innocently: "Commander Zhang, Commander Zhang sent her here, and her women's team came with him, and they brought two T72 tanks."

Lu Xuan's face darkened, and just as he was about to explode, Zhao Min saluted Lu Xuan first, and said, "I was ordered by Commander Zhang of the Shudu Military Region to assist Comrade Lu Xuan in developing new tanks, and at the same time continue to serve as Comrade Lu Xuan's orderly. "

"I don't want an orderly. I can take care of myself. You can go back." Lu Xuan flatly refused.

Zhao Min is very beautiful, and it's very eye-catching to be around, but Lu Xuanxiao can't bear it.

Lu Xuan himself felt that it was outrageous to let Zhao Xingguo, the commander of the Kyoto Garrison and the daughter of the Weapons General Staff Headquarters, be his orderly.

At the same time, he didn't want to do anything by himself, and there were a pair of eyes staring at him.

"Sorry, Comrade Lu Xuan, if you have any dissatisfaction with this order."

"You can respond to Commander Zhang of the Shudu Military Region, or Minister Zhao of the Weapons General Staff Department."

"Until the superior leader revokes this order, I will be your orderly."

Zhao Min stood upright, expressionless, and looked like a soldier who obeyed orders.

The corners of Lu Xuan's mouth twitched. Commander Zhang and Minister Zhao arranged for you. Is it useful for me, a little battalion commander, to respond?

Lu Xuan rolled his eyes at Zhao Min, turned to look at Liu Dayong who had a strange expression on his face, and asked, "You just said that the Shudu Military Region brought two T72 tanks?"

Liu Dayong replied: "Yes, Battalion Commander, Commander Zhang hopes that you will develop new tanks with excellent performance."

"Base 618 is not a tank research and development base. What kind of tank is it developing?" Lu Xuan was speechless.
