利用SEM,TEM,XRD及能谱分析研究了铸态和液态模锻ZA12,ZA27合金的显微组织,结果表明液态模锻不仅使晶粒细化,还具有固溶强化和弥散强化的强韧化效应经液态模锻后,富铝α相中Cu增多,断口形貌转变为韧性断口
The microstructure and phase constituents of ZA12 and ZA27 alloy prepared by casting and liquid metal forging process have been comparatively researched by means of SEM, TEM, XRD and energy spectrum analyses. The results show that the microstructure has b
