1915 Chem. Abstr. 9 437 A martensitic structure is produced in 0·28% C steel without increase in hardness by heating to white heat and then cooling slowly.
1937 Discovery May 153/2 Carbon is mainly responsible for the characteristic martensitic mode of hardening.

1967 A. H. Cottrell Introd. Metall. xvii. 265 When steel is quench-hardened..the F.C.C. austenitic structure then transforms by shear, with some dilatation, into martensite, the distorted form of B.C.C. iron... In recognition of this, shear transformations are often referred to as martensitic transformations.
1989 A. C. Davies Sci. & Pract. Welding (ed. 9) I. ii. 97 The Critical Cooling Rate for a steel is the lowest rate at which a steel can be quenched to give an all-martensitic structure.
