在向变形镁合金中添加Mg-Nd、Mg—Y、中间合金时,常常因为Mg—Nd、Mg-Y中间合金中Nd、Y的品位问题,而影响变形镁合金性能的提高或改善,本试验,以Mg—Zn—Zr—Nd、Mg—Zn—Zr—Y系变形镁合金为例,重点研究了Mg—Nd、Mg—Y中间合金中Nd、Y的品位对其性能的影响,结果指出,Mg—Nd、Mg—Y中间合金Nd、Y的品位高于80％时,合金的室温拉伸性能较佳,反之,则合金的室温拉伸性能低劣。
When adding Mg-Nd, Mg-Y, and master alloys to deformed magnesium alloys, the quality of the deformed magnesium alloys is often improved or improved due to the problems of grade of Nd and Y in the Mg-Nd and Mg-Y master alloys Taking Mg-Zn-Zr-Nd and Mg-Zn-Zr-Y wrought magnesium alloys as an example, the effects of Nd and Y grades on the properties of Mg-Nd and Mg- It is pointed out that when the grade of Nd and Y of Mg-Nd and Mg-Y master alloy is higher than 80%, the tensile properties of the alloy at room temperature are better, on the contrary, the tensile properties of the alloy at room temperature are inferior.
