state of extrusion
Introduction
The phenomenon of plastic deformation occurs when forces applied to a material cause it to undergo permanent shape changes. Over the years, scientists have studied this phenomenon extensively in order to better understand the underlying physical processes, as well as to identify meth......

The meaning and characteristics of IF steel and the quality control in the process
Introduction
IF steel, or interstitial free steel, is a type of steel that is free from interstitial elements, such as oxygen, nitrogen, and hydrogen, which often exist in steel as a result of the steelmaking process. IF steel is commonly used for auto body panels, due to its excellent formabilit......
The formation process of eutectic group
Abstract:
The formation of polycrystals is a complex and fascinating process involving a wide range of physical, chemical and metallurgical phenomena. This article examines the fundamental principles governing the formation of polycrystals and discusses the key processes involved in the formation ......
Brucite (brucite)
，应该怎么写？
Brucite is a mineral form of magnesium hydroxide, with the chemical formula Mg (OH)2. It is a light to dark greenish-grey mineral and is often found in the form of fibrous lath, vitreous, or foliated masses. It is named after the American mineralogist Archibald Bruce.
Brucite is ch......
Ultra-high strength FeMnTWIP1000 steel
TWIP steel whose full name is Twisted Width-Independently Orient Properties steel is a high strength form of steel. TWIP stands for ‘twisted width independly orientable properties’ and is also known as ‘Two- Phase Steel’. TWIP steel is a relatively recent development in the steel industry and ......
Metallographic diagram of 50 steel (hot rolled)
Introduction
20Mn50 steel is a medium carbon, high manganese, low alloy steel. It is heat treated to produce a variety of properties, such as improved toughness, ductility, strength, hardness, and wear resistance. It is commonly used in tools, dies, and machine parts. In this study, a Metallograp......

Microstructure examination of AISI 403 steel
AISI 403 steel is a martensitic stainless steel known for its high wear resistance and corrosion resistance. In order to better characterize its properties, a microstructure examination was conducted on this material. A 2.2 mm thick specimen of AISI 40......
Metallographic structure of 86CrMoV7 cold rolling work roll electroslag ingot
Abstract
The present research study was conducted to investigate the composition and microstructure of the 86CrMoV7 cold-work rolls’ steel billet. To identify the appropriate composition and properties of the material for production of cold work rolls, a thermite process was adopted for refineme......
Metallographic diagram of 30Mn (annealed)
The microstructure of a 0.30Mn (annealed) steel was determined by optical and electron microscopic techniques. Optical microscopy (OM) was used to examine the surface of the steel and the microstructure in the as received condition. In the as received condition, the microstructure was a mixture of......
Twin bands in the microstructure after quenching
Twins in Metals After Quenching
Metals, when quenched, frequently show the formation of twin structures. Twins are lattice patterns that form within a metal as it cools, allowing it to exhibit greater strength and ductility. In some metals, like stainless steel and titanium, this occurs naturally......
