IN-SITU NEUTRON DIFFRACTION AND ACOUSTIC EMISSION INVESTIGATION OF MICROSTRUCTURE EVOLUTION IN MAGNESIUM

Abstract

Acoustic emission and neutron diffraction has been used for investigation of twinning activity and internal stress in random textured polycrystalline magnesium. It has been shown that loading mode significantly influences the evolution of twins and activation of slip systems.

Experimental data are in good agreement with results of Elasto-Plastic Self-Consistent (EPSC) modeling.
