Abstract
AZ31 Mg alloy samples were processed by the equal channel angular pressing (ECAP) process at 200 °C for up to four passes. Microstructural evolution during ECAP was studied systematically using optical microscope and transmission electron microscope. Using data observed from the microstructure analysis, a model for the grain refinement mechanism of Mg during ECAP is proposed. Multiple pass ECAP was also conducted at different temperatures to further confirm the proposed model.
