摘要
用光学显微镜和扫描电镜能谱分析仪,研究了微量元素对ZA合金铸态组织的影响;用硬度、拉伸和耐磨试验探讨了微量元素对ZA合金力学性能的影响,结果表明,微量元素的加入使ZA合金的铸态组织发生了变化,特别是加Ti的ZA合金组织变化较大,同时使ZA合金的硬度、强度和耐磨性均有所提高,
The effect of tiny elements on cast structure of ZA alloy has been studied by microscope and SEM energe analysis meter and then mechanical propecties have been discussed by hard,tensile andwear testing.The results show that the hardness,strength and wear resistance of ZA alloy can beincreased by adding tiny elements to it.There are big changes in cast structure of ZA alloy.
