Chapter 8 Overcoming Titanium Alloy Synthesis Technology

TC4 titanium alloy contains titanium, iron, carbon, nitrogen, hydrogen and oxygen, aluminum, vanadium and other elements. Compared with TC 2 pure titanium metal, titanium alloy is excellent in corrosion resistance and not easy to bend.

Pure titanium metal does not contain any elements, but its hardness is not high.

Titanium alloy is composed of multiple elements, of which titanium accounts for more than 50.00%, and other elements are less than 50.00%.

Based on this knowledge, Li Youchen knew very well that there was no alloy technology in China at the moment.Due to the overseas technology blockade, alloy technology gradually began to be discovered and introduced in the [-]s.

But isn’t it too early to develop titanium alloy synthesis technology now?
At present, the core structural technology of the F-16 fighter jet is only 20.00% away from completing the analysis.

As for titanium alloy synthesis technology, as long as the knowledge sources collected this time are consumed, it can be redeemed, allowing domestic research and development of metal synthesis to be realized in advance.

Li Youchen faced two choices: one was to wait for the analysis of the core structural technology of the F-16 to be completed, and the other was to exchange for the synthesis technology of titanium alloy now.

How to choose?This gave Li Youchen a headache.

Both are important, but thinking about the conditions for breaking through the limitations requires synthetic technology.

There was no hesitation in choosing titanium alloy synthesis technology.

Li Youchen consumed [-] knowledge sources to store the knowledge about the synthetic structure of titanium alloys in his mind, and clearly remembered the required elemental components, including the detailed proportions of each, to formulate the step-by-step synthesis of titanium alloys.

However, he needs precision equipment for processing.

The process follows steps and is very complicated.

Go take a look. Is there any laboratory that specializes in developing the periodic table of elements?

……

The Polytechnic University has a laboratory dedicated to developing the periodic table of elements. It has never been able to study metal synthesis technology.

In the past 80s and [-]s, the slogan "Practice is the only criterion for testing truth" was proposed, and many people's pursuit of truth began with practice.

As a state-owned university of science and technology, the pursuit of scientific truth is carried out in practice. Due to the overseas technology blockade, many people have conducted a lot of research on known technologies that are not available.

Among them, metal synthesis technology is a group of teachers from the Polytechnic University who lead college students to specialize in and overcome this aspect.

Unfortunately, no real progress has been made.

Li Youchen found this laboratory, but if he wanted to use the precision equipment inside, he needed to follow the process and apply for permission before he could use it.

Outside the laboratory door, in the corridor.

After making a call to Teacher Zhao, Li Youchen vaguely felt that he could ask Teacher Zhao for help.

After answering the phone.

Zhao Hong asked: "Who is it?"

Li Youchen replied: "It's me, Teacher Zhao."

Zhao Hong's tone was startled: "It's you! What's wrong? You called me suddenly."

"No! Could it be that the foreigner from before came to my place to look for me again?"

Li Youchen explained: "I came here once, but I drove him away halfway."

Zhao Hong said in a relaxed tone: "That's good."

"That's not right. Why did you call me suddenly?"

Li Youchen explained further: "I want to apply for and use machine tool equipment from the laboratory in the school. I don't know if it is possible..."

Before he finished speaking, Zhao Hong replied quickly: "The teacher immediately called Teacher Qian in the laboratory to agree to your use of the laboratory equipment."

"Wait a mininute……"

After the call was hung up, Li Youchen's feature phone went into a hung-up state.

After resting the screen.

A few minutes later, Teacher Qian quickly walked out of the laboratory.

Li Youchen, who was still in the corridor, squinted at the teacher who came out of the laboratory: "Sorry, Teacher Qian, I would like to apply for the use of metal synthesis machine tools."

Teacher Qian nodded and gestured sideways toward the door:

"Feel free to use it. I understand your situation and you can use it unconditionally."

Li Youchen's head was full of questions. Why did Mr. Qian, who was in charge of the laboratory, sound so polite?Suddenly I felt that I had lowered myself deliberately.

"Thank you."

After thanking him, Li Youchen walked towards the laboratory, still very confused:

Normally, teachers cannot lower themselves when facing students.

As everyone knows, this is Zhao Hong's deliberate arrangement.

A few minutes ago, Teacher Qian learned about the special nature of Li Youchen told by Zhao Hong. No matter what research he does, he must support it unconditionally.

What's more, he will become a real scientific research talent in the development of fourth-generation fighter jets.

After all, he had already taken the lead in drawing the appearance design of the fourth-generation fighter jet.

The concept of stealth design was proposed.

No matter what Li Youchen does, he must be given support within his functional scope.

inside the laboratory.

Li Youchen stared at the two machine tools and reached out to touch the surface. Some of them were rusty, revealing the color of egg yolk. They were old equipment that had been used for a long time, at least ten years ago.

A welding machine is a device that heats metal parts to the melting point and uses filler materials to fill the gaps and connect the two.

A brazing machine is a device that heats metal parts to the melting point of the flux and uses the flux to join two metal parts.

Metal synthesis technology is indispensable for their assistance.

However, the equipment is always a bit old, so there should be no problem in manufacturing titanium alloy elements.

"Teacher Qian, are there any metal elements?"

"Titanium, iron and other powders."

Li Youchen asked Teacher Qian if there was one, it could be made in one step.

"It's all on the bookshelf over there. Except for a few metallic elements in the periodic table, everything else is there." Teacher Qian pointed to the bookshelf and told him.

Li Youchen walked slowly to the bookshelf and looked at dozens of bottles of separately packed metal element powders with stickers on them so that he could tell which element was which.

According to the materials required for titanium alloy synthesis, several metal elements such as titanium, iron, and aluminum were selected.Several can-shaped glass bottles were placed on the table. Li Youchen immediately put on a mask, goggles, protective gloves, and a long white coat.

Returning to the table, Li Youchen began to proportion several different metal elements.

Titanium element accounts for a relatively large proportion, 50.00%.

Seven elements including iron, carbon, nitrogen, hydrogen, oxygen, aluminum, and vanadium each account for 40.00% of the total, and are put into several different containers.

A few bottles and put them back.

Li Youchen took the container to the welder and began to dissolve the metal elements...

Teacher Qian looked at his skillful steps and felt that he was confident in making what alloy element?

But I still don’t know what element synthesis is being done?
Teacher Qian heard footsteps in the corridor, and immediately turned around, closed the curtains, closed the door, and locked the door.

Forgot to ask a group of students led by him to develop the synthesis of metal elements today.

Right now, others are still doing experiments, so other students cannot be allowed in at this time.

The reason told by Zhao Hong was that no matter what experiment Li Youchen did, Teacher Qian had to keep it secret, at least not let others see what experiment Li Youchen was going to do.
