=================================================================================

"Martensite" is named after the German metallurgist Adolf Martens (1850–1914). The generic term, martensite, refers to a class of microstructures formed by diffusionless phase transformation in which the original and formed phases have a specific crystallographic relationship. In the alloys where the solute atoms occupy the interstitial positions in the martensitic lattice (e.g. carbon in iron), the structure is hard and highly strained; but where the solute atoms occupy the substitutional positions (such as nickel in iron), the martensite is soft and ductile. The degree of high-temperature phase that transforms to martensite by cooling depends significantly on the lowest temperature reached.
