摘要: Abstract The effects of Pd on the microstructure and mechanical properties Mg–6Al–1Zn alloys were investigated. Mg–6Al–1Zn–xPd (x = 0–6 wt.%) prepared using a permanent mould casting method. as-cast was characterized by presence Mg17Al12 Al4Pd phases. volume fraction phase increased addition 1–6 wt.%Pd but phases decreased. At room temperature, tensile strength with increasing up to 2 wt.%Pd, elongation fracture decreased concomitant increase in aggregation coarse phase. 150 °C, Pd. Therefore, elevated temperature can be improved addition.
