Role of Grain Boundary Segregation in Texture Weakening of Mass-Produced Mg-Al-Zn-Ca Alloy Sheet Coils
The role of grain boundary segregation in texture modification in mass-produced coils with high formability was investigated. In contrast to commercial Mg-3Al-1Zn (wt.%) alloy, texture weakening was observed in Mg-(1, 2, and 3)Al-1Zn-0.7Ca (wt.%) alloys sheets, which was contributed to solute segregation effect on grain boundaries. Moreover, texture weakening was more promoted by reducing Al contents in Mg-Al-Zn-Ca alloys sheets, leading to the highest index of Erichsen value of 9.1mm at room temperature.
