Texture Aspects of Deformation Processes under Equal-Channel Angular Pressing of Metals

Abstract:

The texture of Ti and Zr rods, subjected to equal-channel angular pressing (ECAP) by routes C and BC, is considered as a source of information about the actual loading scheme, operating mechanisms of plastic deformation, the structure condition of material. Processes of grain reorientation under rolling and ECAP are compared and distinguishing features of the latter are revealed. Effects of grain fragmentation and dynamic recrystallization on the texture are discussed.
