A Summary of the Present Diffusionist Views on Bainite

抄録

The bainite transformation is here considered to be a nonlamellar, competitive form of eutectoid decomposition reaction, taking place by means of ledgewise diffusional growth. The differences between this diffusional, microstructurally oriented approach and a definition evolved from a shear-based transformation mechanism are summarized. The various morphologies of microstructurally defined bainite are described, and the factors affecting their growth kinetics are reviewed. Finally, explanations for the peculiarities associated with the transformation at intermediate reaction temperatures in certain alloy steels are presented.
