摘要

he studies realized show that a plastic deformation modifies the kinetics of the transformation #beta#->#alpha# of the #beta#-Cez alloy. A shift of the U curves towards shorter times is observed for transformation temperatures higher than 750 deg C. However, the kinetics are slowed own for lower transformation temperatures. The amplitude of the effects is linked to deformation ratios and the deformation temperature. The quantitative microstructural study shows that the nucleation kinetics of #beta#->#alpha#_(GB) is accelerated. In addition, a calculation model of the evolution of the transformation kinetics #beta#->#alpha#_(GB)+#alpha#_(WGB) and #beta#->#alpha#_(WI) during continuous cooling is presented.
