Note: The TTT diagrams for MIL A46100 steel equilibrated initially at: (a) 993 K; (b) 1003 K; (c) 1053 K; (d) 1076 K; and (e) 1330 K.
Symbols Fs, Ff, and Bs are used to denote the locus of the temperature vs. time conditions at which austenite begins to transform, respectively,
into allotropic ferrite, acicular ferrite, and bainite. Symbols Ac3, Ac1, Ms, and Mf have their common meanings.
