[f. martensite + -ic.]
Pertaining to or containing martensite; resembling the structure or mode of formation of martensite.
| 1909 in Cent. Dict. Suppl. 1915 Chem. Abstr. IX. 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. 1950 J. Osborne Dental Mech. (ed. 3) xii. 222 Two types of stainless steel find application in dentistry, Martensitic and Austenitic steels. 1967 A. H. Cottrell Introd. Metall. xvii. 265 An important example of a shear transformation occurs 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. |
Hence martenˈsitically adv., in a martensitic manner.
