Effects of grain size and pressing speed on the deformation mode of commercially pure Ti during equal channel angular pressing

Abstract

Inyoung Kim et al study the effects of grain size and pressing speed on the deformation mode of commercially pure titanium during equal channel angular pressing (ECAP). ECAP is now applied to most metals and alloys regardless of crystal structure. The present microstructural examination revealed that the accommodation mechanism of a large strain induced by ECAP changed from deformation twinning to dislocation slip by decreasing the grain size or the pressing speed.
