Variations in microstructure and bending formability of extruded Mg–Al–Zn–Ca–Y–MM alloy with precompression and subsequent annealing treatment conditions

In this study, the bending formability of an extruded Mg–9Al–1Zn–0.3Mn–0.9Ca–0.6Y–0.5 MM (AZXWMM91100, wt%) alloy at room temperature is significantly improved through application of a combined precompression and subsequent annealing (PCA) treatment. As the amount of precompression applied along the extrusion direction (ED) (i.e., the total strain) increases from 4% to 6%, the area fraction of ED-oriented grains of the PCA-treated alloy...
