[f. Edgar C. Bain, U.S. metallurgist (b. 1891) + -ite1.]
A constituent produced at a certain stage in the heat treatment of steel (see quot. 19391).
1935A. Sauveur Metallogr. & Heat Treatm. Iron & Steel (ed. 4) xv. 235 This..constituent microscopically resembles somewhat tempered martensite although its properties are distinctly different... The associates of Bain at the Laboratory at which he was formerly located designate it as ‘Bainite’. 1939E. C. Bain Alloying Elem. in Steel ii. 41 These structures known as ‘bainite’ formed at temperatures roughly between 1000 and 380 degrees Fahr. (500 and 150 degrees Cent.) in carbon steel have interesting mechanical properties, being tougher for the same hardness than tempered martensite. 1939Jrnl. Iron & Steel Inst. CXL. 107 The extreme types differ fairly considerably from each other, for which reason certain writers have separated them into ‘upper bainite’ and ‘lower bainite’. 1954Gloss. Terms Iron & Steel (B.S.I.) I. 6 Bainite, the constituent produced when austenite transforms at a temperature below that at which pearlite is produced and above that at which martensite is formed. 1956Nature 3 Mar. 420/2 Bainite reactions..and the stabilization of austenite. |
