The influence of dynamic recrystallization on flow stress during deformation based alloys Ti—Si—Al—Zr

Abstract

On the alloys of the Ti—Si—Al—Zr studied the effect of the presence of particles of silicide on the course of dynamic recrystallization. Studied the effect of deformation conditions on the deformation mechanism and the formation of structure. It is shown that the presence of particles of the silicide alloy hardens almost in two times in the temperature interval 20—600 ° C, promotes the dynamic recrystallization at higher temperatures, and grinding grain structure. The sharp weakening of alloys with particles above 600 °C silicides explained by a change in the deformation mechanism. Having all the features of a superplastic deformation indicates a growing contribution to the deformation mechanism of grain boundary sliding. Full text download
