mar·ten·site

 (mär′tn-zīt′)
n.
A solid solution of iron and up to one percent of carbon, the chief constituent of hardened carbon tool steels.

[After Adolf Martens (1850-1914), German metallurgist.]

martensite

(ˈmɑːtɪnˌzaɪt)
n
(Metallurgy) metallurgy a constituent formed in steels by rapid quenching, consisting of a supersaturated solid solution of carbon in iron. It is formed by the breakdown of austenite when the rate of cooling is large enough to prevent pearlite forming
[C20: named after Adolf Martens (died 1914), German metallurgist]
martensitic adj
ˌmartenˈsitically adv

mar•tens•ite

(ˈmɑr tnˌzaɪt)

n.
a magnetic microconstituent of carbon steels, formed by decomposition of austenite: found in all hardened tool steels.
[1895–1900; after Adolf Martens (d. 1914), German metallurgist; see -ite1]
