摘要

ZK60合金具有较高的强度和良好的塑性。为进一步提高其性能

在ZK60镁合金的基础上添加少量稀土元素Y和Nd或Ag

并对熔体进行超声处理。研究超声对添加不同元素后的ZK60镁合金凝固组织的影响规律。结果表明

未超声处理时合金元素对晶粒细化效果不明显

ZK60-1Y-1Nd合金、ZK60-1Y合金甚至有粗化现象;稀土元素与超声处理交互作用对晶粒细化明显;经200W超声处理的ZK60-X合金晶粒最小;ZK60+1Y+0.5Ag、ZK60+0.2Nd合金对超声处理的热效应敏感性低。

Abstract

ZK60 exhibits a higher strength and good plasticity in commercial magnesium alloys.In order to further improve its performance

trace Y and Nd rare earth elements or Ag were added into ZK60 magnesium alloy

and then the alloy melt was treated by ultrasound to understand effect of ultrasonic treatment on solidification microstructures of ZK60 alloys with trace Y and Nd or Ag.The results show that refining effects of adding trace elements on the ZK60 alloy can be ignored

and coarse behavior in ZK60-1Y-1Nd and ZK60-1Y can be observed.Coarse grain in the ZK60-1Y-1Nd can be refined by ultrasonic treatment.There exists interaction of RE element and ultrasonic treatment on grain refinement.The minimum grain size can be observed in the ZK60 alloy with Y and Nd or Ag after ultrasonic treatment with 200 W.ZK60-0.2Nd alloy and ZK60-1Y-0.5Ag alloy have low sensitivity to thermal effect of ultrasonic treatment.
