摘要:
Microstructures and mechanical properties of the extruded Mg-1Nd-1Mn-xZn (NMZ11x, x = 0, 1 and 2 wt.%) alloys were explored. The NMZ110 alloy exhibits a partial dynamically recrystallized (DRXed) microstructure containing fine DRXed grains and coarse unDRXed grains. 1 wt.% Zn addition leads to more uneven distribution microstructure and then becomes uniform microstructure after 2 wt.% Zn addition. This phenomenon is attributed to the altered Mg12Nd particle size and distribution. The volume fractions of Mg12Nd particles were raised with the increase of Zn addition and the distribution of coars...
