Martensite
Detailed information:
The chief constituent of hardened carbon tool steels. It is a solution of carbon or Fe₃C in β-iron, or an exceedingly fine-grained α-iron with carbon or Fe₃C in atomic or molecular dispersion. Carbon content up to 1%; easily obtained by quenching small bodies of hypereutectoid steel in cold water; more difficult to obtain in low-carbon steels.
