DeutschAustenite - Simple English Wikipedia, the free encyclopedia
Austenite is iron but in a metallic form. It is one of the allotropes of iron, which means its physical form is different from iron, but its chemical form is the same.[1][2] It is named after Sir William Chandler Roberts-Austen (1843–1902).[3]
Austenitization
[change | change source]Austenitization means to heat iron, iron-based metal, or steel to a high temperature. At that temperature, the crystal structure of the metal changes from ferrite to austenite,[4][5] which can dissolve more carbon.
For some irons, iron-based metals, and steels, the presence of carbides may occur during this austenitization step. The term commonly used for this is two-phase austenitization.[6]
