| Abstract: | The influence of rare earth oxide on the mechanical properties of high Al Zn-based alloy at room and elevated temperature was investigated,and the microstructure and fracture morphology were studied using SEM.The result shows that rare earth oxide play a dispersion-strengthening role on Zn-Al alloy.The strength and the hardness increase 33%and 30% respectively,the strength at elevated temperature improves slightly,but the rate of elongation decreases. |
