Chapter 136 Chrome 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. In this case, it is used to make turbine blades or moving blades of steam turbines. Naturally, there is no second result other than fracture and collapse.
But it’s no wonder that they did it. From piston steam engines to steam turbines, the gap was at least nearly a hundred years. It can almost be said that it spanned from the first industrial revolution to the second industrial revolution.
Not to mention, Perficott 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.
However, 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 helpless assistants, Purficott sternly reprimanded: "Do you all have mouths on your necks for eating? What are your eyes for?
< br>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 were just piling up the hardness? ”
To be honest, for these assistants, being pointed at and scolded by a fourteen-year-old girl is somewhat embarrassing and embarrassing.
But the other party He is an earl, a master of alchemy, and a royal chartered alchemist. These are enough for her to point her nose at these assistants, not to mention that Perficott once applied for the position of professor in the alchemy department of Royal Langton University. .
Although she was not able to get the teaching position, being able to apply for it was enough to show her knowledge and ability.
So, Perfico just pointed at them like this. Even if they do something even more extreme, they can only bear it
However, although Purficott scolded him, he still gave a solution to the problem.
“Add chromium into the material formula to make it hard, but also tough enough to resist wear and corrosion!” Purficott carefully recalled what he had learned before traveling through time. , a solution is given.
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.
Perfect remembers this because she once had an anatomical model of a steam turbine in the original world, which contained a detailed instruction manual introducing the structure, materials and other information of the steam turbine.
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, things went counterproductive. Purficott did not expect that they could not do such a simple job well.
Although it is normal for experiments to fail, their completely deviated thinking really needs to be scolded.
"Chromium? I've heard of this material. It's said to have been discovered by a French alchemist, but they haven't figured out the use of this new material yet." An assistant seemed to be in Perth 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 motioned to the people in front of him with his eyes: "Since you know, why don’t you go to work quickly?"
Then, she He re-examined the steam turbine that he had made, and saw that there were many signs of damage and repairs inside. It was estimated that these were left by the assistants in previous experiments, so he could only sigh. She started 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.
So necessary repairs are still needed, which is not a big deal for Perfectcott.
While doing this, she still felt a sense of inadequacy.
Because she also knew that the steam turbine she made was actually just a lookalike. 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 traveling through time 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.
