Abstract

Magnesium alloyMagnesium alloy sheets generally show a strong basal textureTexture, resulting in a poor formabilityFormability due to their hexagonal closed-packed crystal structure having an axial ratio of 1.624, which is closed to the ideal value of 1.633. Lots of attempts have been made in order to improve the formabilityFormabilityofMg Mg alloy sheets by the addition of alloying elements (Ca/RE with Zn) or applying severe plastic deformation (ECAP, HPT, etc.). In this study, the textureTexture evolution of Mg–Zn–Zr and Mg–Zn–Zr–Gd alloys during the thermo-mechanical treatmentThermo-mechanical treatment have been analyzed and compared in detail. The modified thermo-mechanical treatmentThermo-mechanical treatment was subjected to achieve similar microstructureMicrostructure and textureTexture evolution in both alloys, resulting in a weakened textureTexture and a comparable formabilityFormability in Mg–Zn–Zr alloy to Mg–Zn–Zr–Gd alloy at room temperature. This study suggests that the formabilityFormability of Mg alloys exhibiting a strong basal textureTexture also can be significantly improved by thermo-mechanical treatmentThermo-mechanical treatment.
