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.]

mar′ten·sit′ic (-zĭt′ĭk) adj.


(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

a magnetic microconstituent of carbon steels, formed by decomposition of austenite: found in all hardened tool steels.
