Influence of Controlled Partial Austenitization on the Structure and Properties of Quenched Alloy Steels

CIM Bulletin, 1960

Attempts have been made to produce hardened structures of a pseudomorphic type in various carbon and alloy steels. In order to obtain martensite with a fine distribution of cementite, an initial structure of fine lamellar or nodular pearlite is required; this may be obtained by conventional means. This is followed by partial austenitization and quenching.
