Martensite is a very hard form of steel crystalline structure. It is named after German metallurgist Adolf Martens. By analogy the term can also refer...

originally described the microstructure as similar in appearance to tempered martensite. A fine non-lamellar structure, bainite commonly consists of cementite...

phases, with three different crystal structures (i.e. twinned martensite, detwinned martensite, and austenite) and six possible transformations. The thermo-mechanic...

high-chromium, high-nickel steels are generally austenitic and unable to become martensite when heat treated, while lower-nickel steels can. Alternative variants...

Martensitic stainless steel is a type of stainless steel alloy that has a martensite crystal structure. It can be hardened and tempered through aging and heat...

The austenite is transformed into martensite, a hard body-centered tetragonal crystal structure. The quenched martensite is very hard and too brittle for...
