Abstract
The development of magnesium alloy includes two key aspects, such as microstructure and texture, which play vital roles in mechanical and forming behaviour. In this study, cross-rolled Mg-5Al-5Sn alloy at various temperatures (350 °C, 400 °C, and 450 °C) with a 60% reduction in thickness was investigated. The effect of cross rolling temperature on the Mg-5Al-5Sn alloy microstructure, texture, tensile properties, and formability was studied. The yield strength increases from 114 MPa to 150 MPa with decreasing rolling temperature, which is attributed to grain refinement phenomena. This finding demonstrates that the AT55 Mg alloy possesses an impact on cross rolling temperature, viz. the formability increases with increases in cross rolling temperature. The alloy processed at 350 °C shows better strength and less formability than that of the alloy processed at 450 °C ( lower strength but good formability at room temperature, with an Erichsen value of 4.3 mm).
