Abstract:TTT diagrams and kinetics curves of bainite formation through up quenching from martensitic state and cooling from high temperature parent phase in Cu-Zn-A1 alloys are established by means of dilatometiy and metallographic inspection.Experimental results show that the kinetics characteristics of bainite formation obey the Austin-Rickett Equation with n= 2.25 for up-quenched specimens and n= 1.80 for specimens cooled from high temperature, and the activation energy of bainite formation is about.110 kJ/mol: corresponding to that of the diffusion of solute atoms.
Key words: Cu-Zn-AI alloy, bainitic transformation, kinetics
