Chapter 323 Give me a sample and I will review it
Gao Zhendong took out two drawings, one as deep as a funnel and the other as deep as a shallow plate: "Go to the warehouse and get the drawings marked WT-1 and WT-2 For the test materials, ask Master Yi Zhonghai to process 10 pieces of each material according to the drawing. No cutting, milling, drilling or other processes are required. Just tell him that this will eventually be made into stamped parts, and he will naturally understand what to do. ”
A knowledgeable person can tell what this thing is by looking at its shape, and can at least recognize one of them, but Liu Rongguo does not recognize it.
If you don’t know it, you don’t know it. This doesn’t stop him from doing things. He just answered, took it and left. He didn’t ask questions that shouldn’t be asked. He understood this.
Gao Zhendong wanted to see if he could change the material of the dressing cover.
The most common material for medicine covers is copper, but it does not necessarily mean that the best material is copper. It is common because it is cheap.
If you have to say that copper is not cheap, let’s take a look at materials that are more suitable than copper in addition to price, and you will know what it means to be expensive.
As a medicine-shaped cover, the material responsible for generating metal jets to penetrate armor should have a high density, high dynamic fracture elongation, good sound speed performance, and good thermal conductivity
Note that it is different from what you imagine. The difference is that based on the principle of armor-piercing bullets, hardness is not very important.
When you see this, do you remember anything?
Oh, yes, gold! !
Gold coin bullets. Real! !
If Gao Zhendong dared to suggest using this thing as a medicine mask, I am afraid that the leaders of the 17th Machinery Department and the National Defense Work Committee would jump up and shovel the wax out of his ears first.
But if you switch to tungsten copper, there is a saying. Although tungsten copper also has flaws, from the perspective of potential, it is better than red copper, and we have more tungsten.
Forget about tungsten-molybdenum alloy, it has potential in theory, but it is enough to deal with tungsten copper first.

“Dingling ring~~~~~~”
Gao Zhendong, who was working, answered the phone. On the other end of the phone was Zheng Liangshu’s voice.
"Lao Gao, good news, we have already produced one of the three types of steel you gave us and delivered it to the Beijing University of Technology. They did a test and were full of praise for the performance of the steel!"< br>
Zheng Liangshu’s opening is good news. For him, if there is this one, the KPI will be stable this year. If the other two are developed, it will be pure profit.
He even felt a little regretful, if only one of these three could be released until next year.
I almost slapped myself when I turned around. What were you thinking?
Gao Zhendong was overjoyed when he heard this. It’s not that this thing is of great significance. Compared with his other achievements, this thing is just mediocre. But, knives, you can have a good knife to play with. Damn it, hehe, even a man finds it interesting.
"Great, please say hello to the Beijing University of Technology and leave me a copy of all the samples they are studying."
Prince Zheng Liang, please tell me what samples to leave for you. One, you just have itchy hands and laugh out loud.
The two laughed and chatted for a few words, and Gao Zhendong said: "Old Zheng, this steel has both hardness and toughness, and has good weather resistance. You can find recommendations for farmers and machinery."
For example, to make a hoe? Plowshare? It's simply not easy to use.
Don’t talk about soil, farming is serious.
Don't say it's expensive. If we classify this type of steel in terms of materials and processes, it's just ordinary goods, not expensive. The premise is that the output is not too small.
I was a little confused by Gao Zhendong's big step. Damn it, it's okay, Lao Gao, his thinking is quite flexible.
Zheng Liangshu, who was a political worker, understood the meaning of Gao Zhendong's words very well.
If the military industry is about protecting the homeland and the country, then Gao Zhendong’s suggestion just now is about serving the people, promoting production, increasing production and income. This meaning has reached a higher level.
"Okay, okay, Lao Gao, this work idea is good, I will do it right away, haha." He agreed wholeheartedly. This is not false and exaggerated, he has really good goods, so there is nothing to be afraid of.
This is also Gao Zhendong’s purpose. This kind of steel must have other uses, but what exactly it is used for. Gao Zhendong has never studied it, and he doesn’t have the leisure to study it. He mentioned it to Lao Zheng and asked him to Wouldn't it be nice for him to take care of this matter?
In this matter, everyone has a bright future.
The two chatted for a while and then hung up the phone. Before hanging up, Zheng Liangshu laughed and said: "I'm going to do the second one, hahaha." The laughter was very contagious. With the success of the first one, he said with a smile. The confidence of the two is simply overwhelming, and it feels like picking it up.

At Beijing University of Technology, a student went to his teacher excitedly with a test record.
"Professor Liu, the test results of the new spear stab are out! Very good!"
Professor Liu, the Liu Gong who was previously responsible for communicating with Gao Zhendong, took the test record and put on the glasses He pushed it up the bridge of his nose and looked carefully.
There is a relatively clear statement that the early domestic bayonets eventually evolved into a structure similar to the 53-type four-edged bayonet, except that there was a difference between three-edged and four-edged. The biggest reason was metallurgical problems. Once it was made long, the rigidity was insufficient. , the problem of easy bending comes out.
The easy bending mentioned here means that if it is bent and does not recover, it will bend under force, but if it is bent and does not recover, it will not work.
Whether this statement is correct or not is unknown, but there is always a certain reason for giving up the edge and making it single-function only for assassination. Anyway, this time Gao Zhendong just solves the steel problem. What the design looks like depends on the designer.
And a side example is, taking the 56 and a half as an example, there are two common types of bayonets, one is a ribbed bayonet, and the other is a dagger-shaped bayonet. Although they are both foldable, The length of the dagger-shaped bayonet is much shorter than that of the ribbed bayonet.
It can be seen that the impact of material on length is still obvious. Otherwise, based on the combat thinking at the time, the thorn distance advantage would not be given up. In other words, in order to gain the thorn distance advantage, thorns were eventually used. Professor Liu looked at the test records and praised them repeatedly.
“Good, the rigidity, toughness, and corrosion resistance are very good, and the resulting bending resistance is also very good. This thing is good. We can rest assured about the gun stabbing, as long as it is based on the feedback Just make some minor repairs."
"Professor Liu, Director Gao said that he would like some spear stab samples to go over and take a look at."
As for Gao Zhendong’s thoughts, The old and smart Professor Liu could probably guess a little bit, and laughed: "Well, that's no problem. You can take a handful of our trial products and let's go visit him."
Sending samples is a trivial matter, and the reason why Director Gao wanted the samples was just that.
The main thing is the design of the firearm, which has reached a certain level. It is also time to communicate with Director Gao so that any problems can be discovered and solved early.
Although the theory is okay on my side, when it comes to practice, I still have to find this kind of killing god who came out of the battlefield and listen to his opinions.
And in theory, Director Gao is not necessarily any worse than himself. The opinions given by such comprehensive personnel are often of great significance.
When I saw Gao Zhendong, he was in his office, drawing something.
Seeing Professor Liu and others coming over, Gao Zhendong collected his things and felt excited. Did he come over with a spear sample?
Sure enough, after Professor Liu sat down, he took out a long stick nearly 40 centimeters long from his pocket and handed it to Gao Zhendong.
"Director Gao, this is the new steel we used you to research and the bayonet for the new gun we trial-produced. Take a look and give us your opinion."
Gao Zhendong happily took it and He took out the bayonet from the scabbard and looked at it carefully with a happy face.
How should I put it? Maybe it was because he was used to seeing short bayonets and long thorns in his previous life. Looking at this long bayonet, Gao Zhendong felt uncomfortable.
The length of nearly 40 centimeters may not sound too long, but a comparison will show the length. This thing is nearly half the length of the AK-47.
It is said to be multi-functional, but obviously the people at Beijing University of Technology have not thought that much about "multi-functional". The back of the knife is serrated, so it is considered multi-functional.
Don’t mention it yet, just say it has many functions.
Probably, just think of this multifunctional bayonet as a 38-cap bayonet with a serration on the back.
This made Gao Zhendong, who originally just wanted to collect it, a little nervous. If you want to say whether this thing is a bayonet, is it a multifunctional bayonet? As much as.
What he didn’t know was that the very small number of trial productions of this thing actually became a treasure in the military collection industry in the future. The reason was that it was small in quantity and of great significance. After all, it was not a chance to see the black history of Jingcheng University of Technology. A lot, this thing is.
No, it has to be changed. This thing has been accepted, but the bayonet still needs to be improved.
Looking at Gao Zhendong's constipated look, Professor Liu said: "Director Gao, this knife?"
Gao Zhendong came back to his senses: "Ah, ah, the knife is good, not bad. "
As soon as Professor Liu saw his expression, he knew that Director Gao was probably not easy to dampen his enthusiasm, so he simply made it clear: "Director Gao, if you have any ideas, just say it, it's okay, I'm still here At the design stage, we are here to listen to your opinions.”
Gao Zhendong nodded, you asked me to say so.
"In this way, I think it can at least add the functions of filing and shearing. In addition, it would also be good to put the whetstone directly on the scabbard."
Professor Liu thought about it, Director Gao's idea, It is the direct opposite of "making a bayonet multi-functional", it is "making a multi-functional knife that can also be used as a bayonet".
This seems to be a good idea. It is a way. Give it a try.
"Director Gao, please tell me in detail, I just want to be a copywriter today, haha."
Gao Zhendong directly told the results of imitating the Citigroup M9 in his previous life, and cut it Cutting edge, shearing plate seat, shaft hole, filing area, flat opening, etc.
After finishing speaking, he added: "This knife is relatively long, so the hardening treatment of the scabbard can only deal with the lower half."
If the scabbard is not hardened, it will not be used when making scissors. How much force.
Professor Liu feels that although these suggestions are simple, they can really solve many problems. Among other things, cutting barbed wire is always needed, even decades later.
He jotted them down one by one with satisfaction. Well, this time the design of the bayonet came together.
Then, he took out another thing: "Director Gao, this is the result of our firearm design so far, please show it."
