OS0113-323 Microstructural Evolution of Rolled AZ31 Magnesium Alloy in Tension and Compression

Abstract

The influence of loading direction on microstructural evolution of rolled AZ31 magnesium alloy (average grain size: approximately 40μm) was investigated. Pseudoelastic behaviors were observed in tensile and compressive loading-unloading tests. The large anelastic strains and work hardening coefficient were observed in compressive stress-strain hysteresis loops of the S specimen. As increasing plastic strain, deformation twins were developed uniformly in tensile loading, on the other hand, deformation twins were developed locally in compressive loading.
