Any crystal structure formed by a martensitic transition
A solid solution of carbon in iron; the chief constituent of steel
A hard supersaturated solid solution of iron characterized by an acicular (needle-like) microstructure
Martensite is a microconstituent or structure in quenched steel characterized by an acicular or needle-like pattern on the surface of polish It has the maximum hardness of any of the structures resulting from the decomposition products of austenite
A ferritic material with distinctive needle like structure which is always present in heat treat hardenable steel
A generic term for microstructures formed by diffusion-less phase transformation in which the parent and product phases have a specific crystallographic relationship Martensite is characterized by an acicular pattern in the microstructure in both ferrous and nonferrous alloys In alloys where the solute atoms occupy interstitial positions in the martensitic lattice (such as carbon in iron), the structure is hard and highly strained; but where the solute atoms occupy substitutional positions (such as nickel and iron), the martensite is soft and ductile T he amount of high temperature phase that transforms to martensite on cooling depends on the lowest temperature attained, there being a rather distinct beginning temperature (Ms) and a temperature at which the transformation is essentially complete (Mf)
The low-temperature phase of some metals, e g NiTi
Low temperature phase of NiTi, exhibits the CsCl crystal structure
A generic term used for microstructures formed by diffusionless phase transformations A constituent found in hardened steel; has a needle like microstructure See also Mf and Ms
The hard constituent produced when steel is cooled from the hardening temperature at a speed greater than its critical cooling rate Martensite is an acicular phase when seen in the microstructure of steel
a solid solution of carbon in alpha-iron that is formed when steel is cooled so rapidly that the change from austenite to pearlite is suppressed; responsible for the hardness of quenched steel
a metastable iron phase supersaturated in carbon that is the product of a diffusionless (athermal) transformation from austenite
a super-saturated solid solution of carbon in ferrite The carbon atoms distort the BCC ferrite into a BC-tetragonal structure
The more deformable, lower temperature phase present in NiTi
Crystal type of iron (magnetic), which is characteried by a cubic body centered lattice structure The acicular and very hard or brittle microstructure is formed, when austenite is quenched at comparably high cooling speeds, so that the carbon has no time for diffusion
A terrific material with distinctive needle like structure which is always present in heat treat hardenable steel

martensitic
Small category of stainless steel characterized by the use of heat treatment for hardening and strengthening Martensitic stainless steels are plain chromium steels with no significant nickel content They are utilized in equipment for the chemical and oil industries and in surgical instruments The most popular martensitic stainless steel is type 410 (a grade appropriate for non-severe corrosion environments requiring high strength)
