Austenite, also known as gamma-phase iron (γ-Fe), is a metallic, non-magnetic allotrope of iron or a solid solution of iron with an alloying element. In plain-carbon steel, austenite exists above the critical eutectoid temperature of 1000 K (727 °C); other alloys of steel have different eutectoid temperatures. … See more From 912 to 1,394 °C (1,674 to 2,541 °F) alpha iron undergoes a phase transition from body-centered cubic (BCC) to the face-centered cubic (FCC) configuration of gamma iron, also called austenite. This is similarly soft and … See more Austenitization means to heat the iron, iron-based metal, or steel to a temperature at which it changes crystal structure from ferrite to austenite. … See more As austenite cools, the carbon diffuses out of the austenite and forms carbon-rich iron-carbide (cementite) and leaves behind carbon-poor See more The addition of certain alloying elements, such as manganese and nickel, can stabilize the austenitic structure, facilitating heat-treatment of low-alloy steels. In the extreme case of See more Austempering is a hardening process that is used on iron-based metals to promote better mechanical properties. The metal is heated into the … See more Heating white cast iron above 727 °C (1,341 °F) causes the formation of austenite in crystals of primary cementite. This austenisation of white iron occurs in primary cementite … See more In many magnetic ferrous alloys, the Curie point, the temperature at which magnetic materials cease to behave magnetically, occurs at nearly the same temperature as the austenite … See more WebOct 14, 2024 · Ist nicht genügend Sauerstoff vorhanden, um sofort Zinkoxid zu bilden, können Zn-Atome die Stahloberfläche erreichen und das Austenitkorn oder die …
