Chapter 31: Fighting rabbits

On the one hand, he asked Chief Li to select 12 militiamen who he thought had the best bayonet skills, and they took turns in groups of four. Gao Zhendong moved around and stabbed 4 of them, leaving himself without a single hit. The entire militia was dumbfounded and silent. Gao Zhendong smiled and said, "My performance is nothing. Comrade Lu Junsheng took on 12 Japanese devils in one battle. He is a god of war."

Section Chief Li applauded and said, "Zhendong, don't be modest. Although the person you mentioned is very capable, I haven't seen him. I saw your skill with my own eyes."

The militiamen: “Ah, yes, yes, yes.”, and applauded loudly.

In his other hand was a gun. He had been eyeing this for a long time. He shot 56 rounds at a 100mm 10-meter target in a standing position, and scored 10 rings every time. The atmosphere became even more lively, and everyone cheered for him. Gao Zhendong was still modest: "My chest target is just average. When the troops had a big competition, they had machine guns and mobile guns and fired rapidly. I shot at a row of head targets one by one, and every shot hit the target."

Section Chief Li really couldn't stand this guy anymore, so he gave him a thumbs up, turned around and walked away, not bothering to support him.

As the saying goes, since you're here and you've exposed yourself, Gao Zhendong just stayed here for a day and had a good time shooting guns. I'm a grown man, so what if I can't walk when I see a gun? Just treat it as a vacation for myself.

In addition to shooting, Gao Zhendong also took over some of the militia training work that day. After all, he was the deputy captain. If he wasn't here, it would be fine. Since he was here, he still had to do some work. It was probably to organize the militia, guide the movements, and train the shooting. Occasionally, he played fighting and wrestling with the militia, which brought back some of the feeling of being in the army.

After get off work in the afternoon, Gao Zhendong, who had gained a lot of prestige and favorability in the militia team, said goodbye to the militiamen and rode his bike home.

After making himself a meal, Gao Zhendong began to worry about the material of the thermocouple protection tube.

Gao Zhendong chose GH2747 deformable high-temperature alloy. Actually, he knew about this thing because he was playing around with thermocouples during his graduation project in his previous life and found it while searching for information.

GH2747 alloy is an iron-nickel-chromium based precipitation hardening deformable high temperature alloy with a long-term working temperature of 1100°C-1250°C and a short-term use temperature of up to 1300°C. It can basically meet the application requirements of K-type and N-type thermocouples.

This alloy has high strength, good organizational stability, excellent oxidation resistance and corrosion resistance, good welding performance, and can also be processed by rolling, forging and other methods. The simplest way to use it in batches on thermocouple protection tubes is to roll it into thin plates, coil it, and weld it.

And this thing is only used in thermocouples for a small purpose. It can be widely used in aerospace, petrochemical, nuclear energy, metallurgy, and is relatively inexpensive. In addition to iron, nickel and chromium, there is only one other material that sounds rare - the light rare earth element cerium. In fact, it sounds rare, but it is everywhere, such as in flint lighters - flint is.

This is actually the second big satellite that Gao Zhendong is preparing to launch, but it is inconvenient to carry out a separate project, and his professional background is not suitable, so he made it in the name of trial production of thermocouple protection tube materials. Because the manufacture of this alloy can choose the vacuum induction furnace process, which is a perfect match with the existing test conditions.

This is called catching rabbits while robbing grass, killing two birds with one stone.

In his previous life, when Gao Zhendong was dealing with thermocouples, he thought that this material was really a good thing. He looked up relevant information out of curiosity and repeatedly read one of the most important contents out of curiosity: material ratio. It's a pity that he couldn't remember all of GB/T 14992, otherwise Gao Zhendong would have been stuck in metallurgy for the rest of his life.

Thinking of this, Gao Zhendong was shocked: It's bad, it's bad, I won't go further and further on the road of metallurgy? No, no, I am an automation, writing bugs is my profession! Making CPU is my ideal!

Throwing aside the nonsensical thoughts that suddenly popped up in his head, Gao Zhendong began to recall and record the information related to GH2747 in his head. It was because his brain had been strengthened by the system, otherwise he would never be able to remember it even if he was beaten to death.

Gao Zhendong was busy when there was a knock on the door.

Gao Zhendong put the recorded information into the storage room, then stood up and opened the door.

There was a deaf old lady outside the door, holding something in her hand. Gao Zhendong quickly asked her to come into the house: "Old lady, if you have any problem, just ask Sha Zhu to call me. It's dark and cold here. I will be blamed if something happens." The deaf old lady smiled with her toothless mouth: "It's okay, old woman, my legs and feet are still nimble, and my eyes can still see. It's just that my ears are not good." As she spoke, she walked to the stove and sat down.

Gao Zhendong smiled: "Old lady, I see that you are a very clear-headed person, not a person with poor hearing."

The old lady pursed her lips and curled her lips: "What did you say? I can't hear you~~~~"

Okay, can you please perform a live performance for me right away?
Anyway, he had almost finished his work, and it was a rare occasion for the old lady to come home, so Gao Zhendong made a cup of malted milk for her.

The deaf old lady took a sip and said, "Mmm, sweet."

Gao Zhendong said loudly: "If you like, drink more. I still have half a can. You can take it away later. It's good for your health."

The deaf old lady nodded: "Well, you are better than Shazhu. Shazhu cooks for me a few times a week, but there is no meat~~~."

Although Shazhu's words sounded like complaints, his tone was actually full of doting.

Gao Zhendong knew that the two of them always talked like this. If he continued to criticize Sha Zhu, the old lady would definitely not be happy. He did not continue to say, "Old lady, what's the matter?"

Hearing this, the deaf old lady picked up the bag in her hand and took out a pair of shoes from it: "I know Zhendong you are a good boy and you really treat me as your elder. I am also old and can't help you much, I can only move my hands. Look, winter is coming soon, I will make you a pair of shoes to warm your feet."

Gao Zhendong did not refuse: "Oh, that's great, I was just worried about not having shoes to wear when the weather gets cold."

As she spoke, she took off her shoes and put them on her feet: "Ma'am, you are amazing. You didn't even measure my feet, but the shoes you made are the perfect size."

The old lady curled her lips and said, "Hmph, I have been making shoes for decades. My ears don't work well, but my eyes are very bright." The old lady really likes to curl her lips, just like a child.

Gao Zhendong took off his shoes cheerfully and put them away: "I told you when I just came into the courtyard that when my parents were still alive and engaged in the revolution, they might have worn the shoes you gave them. This time, I am wearing the shoes you made, too."

The old lady smiled and said, "Well, if you like it, I will make it for you every year."

"That's great. Let me thank you first." Gao Zhendong was not polite at all. This was because he had just joined the army. Otherwise, he would have violated the discipline of "not taking a single needle or thread from the masses."

He also chatted with the old lady for a while about the gossip in the courtyard, such as Liu Haizhong beating up the second son Liu Guangtian, Yan Bugui scheming against the eldest son Yan Jiecheng, Jia Zhang scolding her daughter-in-law Qin Huairu, and He Yuzhu easily taking Xu Damao from the backyard. Gao Zhendong was so excited that he danced with joy.

Seeing that the old lady had finished drinking the malted milk and it was almost time, Gao Zhendong took the half can of malted milk and sent the old lady back to the backyard.
