Metallographic observation has directly revealed the continuous motion of the bainite/austenite interface in a manner consistent with the achievement of thermoelastic equilibrium. Further observation demonstrates that the shear deformation associated with the growth of bainite can induce mechanical twinning in the surrounding microstructure in appropriate circumstances. For the purposes of comparison, analogous observations for martensite are also reported.
