1935 A. Sauveur Metallogr. 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’.
1939 E. 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.
1939 Jrnl. Iron & Steel Inst. 140 107 The extreme types differ fairly considerably from each other, for which reason certain writers have separated them into ‘upper bainite’ and ‘lower bainite’.
1954 Gloss. 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.
1956 Nature 3 Mar. 420/2 Bainite reactions..and the stabilization of austenite.
