Carburizing, also known as a case-hardening process, is a heat treatment process used to harden the surface of low carbon steel parts by infusing carbon into the surface layer of the steel. This process enhances the surface hardness and wear resistance while maintaining a tough and ductile interior. The process is crucial in applications where the wear resistance of the material is critical, such as gears, camshafts, and other high-stress components.

The primary purpose of carburizing is to increase the carbon content at the surface of a low-carbon steel part.

Machine learning uses X-ray diffraction data from polymers to predict the behavior of new materials

Polymers such as polypropylene are fundamental materials in the modern world, found in everything from computers to cars. Because of their ubiquity, it's vital that materials scientists know exactly how each newly developed polymer will perform under different preparation conditions. As described in a new study, which was published in Science and Technology of Advanced Materials, scientists can now use machine learning to determine what to expect from a new polymer. Predicting the mechanical properties of new polymers, such as their tensile strength or flexibility, usually involves putting them through destructive and costly physical tests. However, a team of researchers from Japan, led by Dr. Ryo Tamura, Dr. Kenji Nagata, and Dr. Takashi Nakanishi from the National Institute for Materials Science in Tsukuba, showed that machine learning can predict the material properties of polymers. They developed the method on a group of polymers called homo-polypropylenes, using X-ray diffraction patterns of the polymers under different preparation conditions to provide detailed information about their complex structure and features.

what would the cowbians be doing with their lives in a modern au? :3

Mattie would’ve gone to juvie as a teen because she set fire to her dads barn. But once she got out she apprenticed under a car mechanic a few states away and eventually became one, she then made a tiktok account showing people how to fix their cars but got internet famous because of how effortlessly attractive she is

Flora would’ve grown up in a very big Italian family in nyc that (as the eldest daughter and first grandchild) expected her to become a doctor or a lawyer and to marry a nice man and have children. Flora did not like that. So she decided to convert a van into a make shift home and drive across the country without telling anyone.

(Can you see where this is going)

Floras car breaks down in the middle of nowhere utah trying to get to California. She needs to get it repaired,, Mattie’s shop is the only one around. Flora doesn’t have any money so mattie offers her a deal: flora helps out around the shop for a few weeks while mattie fixes the car

(Flora and mattie keep finding more reasons for her to stay “the break pedal is kinda sticky, what’s an oil change? The radio won’t turn on etc”)

They fall in love

What is the forging process?

Forging is the working of metal into a useful shape by using localized compressive forces. These forces are applied through various tools such as hammers or presses. This process is integral to producing high-strength components for various industries, including automotive, aerospace, and construction.

Most forging operations are carried out hot, although certain metals may be cold forged. Two major classes of equipment are used for forging operations: the forging hammer, or drop hammer, which delivers rapid impact blows to the surface of the metal, and the forging press, which subjects the metal to a slow speed compressive force.

Researchers reveal new method for calculating mechanical properties of solids using machine learning

A research team from Skoltech introduced a new method that takes advantage of machine learning for studying the properties of polycrystals, composites, and multiphase systems. It attained high accuracy, nearly as good as that of quantum-mechanical methods, which are only applicable to materials with less than a few hundred atoms. The new method also benefits from active learning on local atomic environments. The paper is published in the Advanced Theory and Simulations journal. "Many industrial materials are synthesized as polycrystals or multiphase systems. They contain both a single crystal and amorphous components between single crystal grains. The large number of atoms makes it hard to calculate the properties of these systems using modern quantum-mechanical methods. Density functional theory can only be applied to materials with a few hundred atoms."
