采用水冷铜模法和水淬法制备得到Mg<,65+x>(Cu<,0.66>Y<,0.34>)<,30-x>Zn<,5>(x=5,10,15)非晶及其复合材料.并通过xRD、SEM对材料结构进行表征,研究Mg含量和冷却速度对样品微观结构的影响.结果表明:由水冷铜模法得到的x=5样品为单一非晶,x=10和15样品是由非晶相与Mg固溶体相组成的非晶复合材料.而利用冷速较低的水淬法得到的样品为非晶复合材料,其主要由Mg,Mg<,2>Cu,MgZnY和非晶相组成.通过研究合金在NaCl中性溶液中的腐蚀行为,发现随着Mg含量的增加,样品的耐腐蚀性能有所下降.并且对于同成分的合金,由冷速较快的水冷铜模法得到的样品耐蚀性相对较好.
