Microstructural Evolution and Mechanical Properties of Pure Magnesium during Multi-Axial Compression

Abstract:

The effects of multi-axial compression (MAC) on the microstructures and mechanical properties of pure magnesium were investigated. It has been shown that grain refinement and grain growth occurred simultaneously during the MAC process. After 5 MAC passes, the grain size is mainly distributed in the range of 5~25 μm. The hardness of the specimens increases with increasing the strain (MAC pass), with the increment at lower strain being more obvious than that at higher strain. Compression tests showed that the samples show significant difference in mechanical properties along different directions due to the texture development. With increasing the MAC pass, the texture has been weakened due to multi-axial deformation.
