Chapter 9: Explanation of titanium alloy synthesis technology (seeking for further reading)
Heated to a certain melting point, titanium is the main element, and seven small amounts of metal powders such as iron and aluminum are added successively into the red liquid titanium. Under high-temperature heating, it has been red-hot and dissolved, and the mixture is integrated.

Turn off the heating of the welding machine and wait for the titanium alloy to gradually cool down from the dissolved state.

Minutes passed by, and about 10 minutes passed.

Li Youchen stretched out his pliers and picked up a very small piece of titanium alloy.

[Successfully produced TC4 titanium alloy, upgrade points +10]

In the left eye, a silent panel displays.

"Success!"

Li Youchen was overjoyed. He followed the steps and combined the dissolution and integration of the eight elements in proportion to create the first titanium alloy material in this era.

"What succeeded? Classmate, what are you doing?"

Teacher Qian walked over and asked.

"Sorry to disturb Teacher Qian."

"I wonder if the teacher has actually seen it? TC4 titanium alloy made by Yingjiang."

Li Youchen apologized and then asked a question.

"I have heard of TC4 titanium alloy, but I have never seen it. Yingjiang has never sold such alloy materials to our country. But I know that the synthesis technology of titanium alloy materials is not currently available in China and is on the market. , and there is no titanium alloy material for sale.”

"The reason for the restriction is that foreign countries have serious technical blockades."

"No, how could you say this?"

Teacher Qian was very curious and asked seriously.

"I say this because I have mastered the titanium alloy synthesis technology."

"The finished product is already in the palm of your hand."

Li Youchen raised the pliers and asked Teacher Qian to see what they were holding.
Teacher Qian walked forward and took a closer look. He saw a very small piece of metal:
"This is titanium alloy. Is this the purpose of the synthesis experiment you just did?"

After cooling is completed, the temperature is no longer above the melting point and returns to the solidified state.

This is a very small piece of metal, which was held between two fingers of Li Youchen's right hand:

"Exactly. Titanium element is 50.00% six, and other mixed elements are 40.00% four. According to a certain proportion, they are dissolved through welding to form a liquid element. Titanium is the main element, mixed with other small amounts of elements, and it becomes this piece of titanium alloy."

Teacher Qian watched carefully, unable to shift his gaze.

Because when he said that titanium is the main element and mixed with other metal elements, it was a situation that he did not expect.At present, relying on the periodic table of elements, few people who are familiar with the periodic table of elements in polytechnic universities and society know about the technology of titanium alloy synthesis.

What's more, he uses a welding machine to create what he calls TC4 titanium alloy.

It is hard to believe that a college student is familiar with the principles of titanium alloy synthesis.

Through proportional blending, the synthesis of titanium alloys can be completed.

It’s hard to believe that this small piece of metal is TC4 titanium alloy made in the United States.

"Teacher Qian, don't you believe it?"

Li Youchen asked, looking at the way he was thinking seriously and couldn't take his eyes away.

"It's hard to believe that this is a titanium alloy. After all, we never know how to mix the proportions and what elements should be added to titanium to synthesize it to make it a truly high-strength titanium alloy."

Although Teacher Qian knows something about this aspect, he has never seriously understood the synthesis of titanium alloys. What elements should be added into the titanium metal?
Li Youchen put the small piece of titanium alloy on the table, picked up the hammer from the side, and hit the small piece of titanium alloy hard!

Clap!
The hammer was bounced off, and there was almost no damage to this small piece of titanium alloy.

Condition, solid.

Teacher Qian looked at it, dumbfounded, "It was not smashed. How is that possible? This piece of metal is really titanium alloy!"

If pure titanium metal is dropped, it will definitely break.Titanium alloy will not, because titanium alloy is mixed with other metal elements, which improves the resistance to a certain extent and is not easy to be smashed by a hand hammer.

Such a small one, if hit a few times, will not have enough resistance and will be smashed by a hand hammer.

Li Youchen picked up the chalk, wrote a few lines in front of the blackboard:
Titanium element, accounting for 50.00%.

Elements such as iron and aluminum account for between six and seven percent respectively.

Teacher Qian walked over and looked at the blackboard.

Obediently stay in your seat, bend down and listen to the lecture carefully.

"Regarding titanium alloys, the proportion of the main titanium element is greater than the sum of other elements. The hardness of the mixture of other metal elements increases by more than 40.00% compared to the hardness of pure titanium metal."

"In terms of resistance, a piece of titanium alloy as wide as two fingers combined can easily resist bullets, and its hardness is higher than some pure metals."

"The second is titanium alloy. Compared with rusty steel, it has very good corrosion resistance. It has high strength, low density and excellent corrosion resistance. The main reason is that it has an oxide film, which can protect the internal metal and prevent other metal elements. Chemical reactions with titanium alloys.”

"..."

Li Youchen gave detailed knowledge about titanium alloys.

Including the synthesis of titanium alloys, it needs to be carried out through proportional mixing.

As for the proportion of elements, titanium needs to account for a large proportion, and other metal elements should account for a small proportion. Depending on the situation, different types of titanium alloys are required, and some unnecessary metal elements can be added.

"So, titanium alloy, there are different styles."

"Generally, titanium alloys used in the development of aircraft and aircraft in the aerospace field have some elements added. It is not necessary to add all eight elements like this finished titanium alloy."

Teacher Qian listened to part of his explanation and repeated it.

"Exactly. It can be said that if you want a titanium alloy with excellent corrosion resistance, the manufacturer will make it according to your needs and cancel the carbon and vanadium among the eight elements to further improve the corrosion resistance."

"Moreover, titanium alloys used in aircraft generally remove the carbon element and retain seven metal elements, because carbon elements are easily affected by oxidation when exposed to open flames, affecting the overall quality of the titanium alloy."

Li Youchen continued to explain the titanium alloy required for manufacturing various aircraft in the aerospace field, and what metal elements should not be required in it. He made it clear to Teacher Qian.

"understood."

Teacher Qian understood the details about the production of titanium alloy like a student.

"Sorry, teacher, I have to go."

"I'm not that good at lecturing, and I'm not qualified to give lectures to teachers."

Li Youchen smiled and scratched his head in embarrassment.

"It's okay. Your lecture is very interesting."

"Speaking of which, when are you guys outside the door planning to eavesdrop?"

It looks like it's made of titanium alloy, so it's not a secret. Teacher Qian doesn't worry that they can eavesdrop on it, but it's better to come in and listen.

The door was pushed open and several people fell forward!
It was Xiao Chen and several other boys, including Bai Qianyu who was standing outside the door with a wry smile.

I was listening to the class outside, enjoying it with great interest, and had no intention of disturbing him.

"Hello teacher."

"Hello teacher."

They were lying on the ground and said hello to Teacher Qian one after another.

Even Bai Qianyu walked in and greeted him politely:
"Hello, teacher, sorry to bother you."

Teacher Qian nodded and did not speak immediately. Instead, he turned to look at Li Youchen.
