Chapter 136 Chromium Stainless Steel

"A bunch of idiots! The harder the blade, the better!" Looking at the experimental report submitted by his assistants, Purficott suddenly cursed angrily.

These guys are obviously over the top. They just blindly increase the hardness of the blade material, so that the entire material becomes very brittle. Under such circumstances, if it is used to make turbine blades or moving blades of a steam turbine, it will naturally break apart and collapse. There is no second outcome other than bad.

But it's no wonder that they, from the piston steam engine to the steam turbine, the gap is at least nearly a hundred years, it can almost be said that it spans from the first industrial revolution to the second industrial revolution.

Not to mention, Purficott designed a multi-stage steam turbine, which further increased the complexity of the machine and the material requirements for the blades.

It’s not like she hasn’t thought about making a single-stage impact turbine to learn the relevant technology, and then make a multi-stage one.

But she didn't have that much time to take it step by step, so she could only make technological leaps by encouraging others.

But she didn't expect that just by asking these assistants to improve the production materials according to her own requirements, they could still create such a trick for herself.

Facing the bewildered assistant, Purficott sternly reprimanded: "Don't you all have mouths on your necks for eating? What are your eyes for?"

My material requirements are clearly written. In addition to hardness, there are also requirements for the toughness of the material!

In addition to having sufficient hardness, this material also needs to be tough enough to withstand the deformation caused by the centrifugal force generated during high-speed rotation! Didn’t you see what I wrote when you just piled up the hardness? "

To be honest, for these assistants, being pointed and scolded by a fourteen-year-old girl is somewhat embarrassing and embarrassing.

But the other party was an earl, a master of alchemy, and a royal chartered alchemist. These were enough for her to point her nose at these assistants and scold them, not to mention that Perficott had also applied for a professorship in the alchemy department of Royal Langton University. position.

Although she was not able to get the teaching position, her knowledge and ability were enough to apply for it.

Therefore, Purfico specifically said that he just pointed at their noses and scolded them like this. Even if he did it more excessively, they could only endure it.

However, although Purficott scolded him, he still gave a solution to the problem.

"Add chromium to the material formula to make it hard, but also tough enough to be wear-resistant and corrosion-resistant!" Purficott carefully recalled the knowledge he had learned before traveling and gave a solution. plan.

1Cr13, martensitic stainless steel, is a metal material widely used in the original world by adding chromium to iron to improve the hardness, toughness and corrosion resistance of the material.

It was originally developed to create a wear-resistant gun bore. It was favored because it had good corrosion resistance and did not rust and was always shiny, so it was made into tableware.

After that, after many years of development, it gradually became a widely used material.

Due to its good performance, this material was also the main material for making steam turbine blades in the original world.

The reason Purficott remembers this is because she once had an anatomical model of a steam turbine in the original world. There was a detailed instruction manual introducing various aspects of the steam turbine's structure, materials, and other information.

It is precisely because of this that Perficott was able to reproduce it in this world without any foundation. Just for the issue of materials, this also involves heat treatment related processes. It is not just about using alchemy to mix two different metals in proportion to create an alloy.

Although this is not impossible, the strength of the material will be somewhat inferior.

But for Purficott, how can heat treatment be as convenient and fast as alchemical processing? Whatever performance is needed, just use alchemy to adjust it.

This is also the main reason why she needs these assistants to work, so that they can improve the materials based on the indicators they provide.

Although she did not come up with the formula for chromium stainless steel at the beginning, she wanted these assistants to use their skills to see if they could surprise herself.

However, what happened was counterproductive. Purficott did not expect that even such a simple task could not be done well.

Although it is normal for experiments to fail, their completely deviated thinking really needs to be scolded.

"Chromium? I have heard of this material. It is said that it was discovered by a French alchemist, but they still haven't figured out what this new material is used for." Feiket showed off in front of him and deliberately told the information he knew.

When Purficott heard what he said, he didn't say anything more. He just pointed his eyes at the people in front of him: "Since you know, why don't you go to work?"

Afterwards, she re-examined the steam turbine she had made, and saw that there were many signs of damage and repairs inside, which were probably left by the assistants in previous experiments, so she could only sigh. After that, she took it upon herself to repair the unsatisfactory repair marks. Otherwise, she was afraid that even with qualified blades, the inside of the steam turbine would probably not be usable.

Therefore, necessary repairs are still needed, which is not a big deal for Perfectcott.

But while doing this, she still felt a sense of powerlessness.

Because she also knew that the steam turbine she made was actually just a fake. Just like the turbine blades were unqualified, the entire machine itself was also unqualified in terms of materials.

But because her usage requirements are not that high, materials of this level can also be used.

After all, Purficott only has so much research on materials. Even if he masters the powerful alchemy, it is very difficult to improve the level of science and technology for a hundred years by himself.

Now she can only rely on the knowledge she mastered before time travel to improve existing materials as much as possible to create higher-performance materials.

As for process issues such as heat treatment of materials to increase strength, she was powerless. She had never been exposed to these things in the original world.

She has a lot of ideas in her mind that are far ahead of this era, but she needs more and more professional people to help her turn them into reality, instead of relying on her to do everything by herself.
