The Influence of Texture and Grain Size on Compressive Deformation Behavior of Pure Mg Through Equal-Channel Angular Processing

摘要

Multi-pass of equal channel angular pressing (ECAP) at a single temperature as low as room temperature from 200 ℃ were measured using electronic back scatter diffraction (EBSD). The effect of texture and grain size on mechanical properties was investigated to realize the strengthening and large plastic deformation mechanism. A room temperature ECAP with multi-pass procedure is effective to product high strength and large plastic Mg, as a result of submicron grain structure and texture strengthening.
