摘要

针对高强耐热的稀土镁合金净化困难、稀土元素损耗大的问题

采用自行开发的熔剂JDRJ-6对GW103K合金进行精炼

研究了不同YCl3含量的熔剂对合金净化效果及Y元素损耗率的影响

并与熔剂JDMJ及RJ-6的综合效果进行了比较。结果表明

经熔剂JDRJ-6+2.5%的YCl3精炼后

Y元素的损耗率和腐蚀速率分别下降至18.12%和0.837mg.cm-2.d-1

而抗拉强度、伸长率则分别提高至226.25MPa和4.86%

达到了预期的净化效果。

Abstract

Aiming at the difficulty in purifying the high strength and heat resistant RE magnesium alloy and in mass loss of RE in the alloy

we have developed a flux JDRJ-6 to refine the Mg-Gd-Y（GW103K）alloy to understand effects of the flux containing varied YCl3 content on purification and mass loss of Y element

and it is compared with JDMJ flux and RJ-6 flux.The results reveal that after refined by JDRJ-6+2.5%YCl3

the loss of Y and corrosion rate of the alloy are decreased to 18.12% and 0.837 mg·cm-2·d-1

respectively

while the tensile strength and elongation are improved to 226.25MPa and 4.86%

respectively

obtaining the expected results.
