Abstract:

一种准晶增强Mg-Zn-Er耐热镁合金及其制备方法属于耐热镁合金材料领域。本发明所提供的合金中各组分及其质量百分比为:Zn为4.5~5.0%,Er为2.0~4.0%,杂质元素Si含量≤0.02%,Fe含量≤0.005%,Cu含量≤0.015%,Ni含量≤0.002%,余量为Mg。本发明通过将预热至140~160℃的镁合金熔炼覆盖剂、镁锭和锌锭加入到200~250℃的坩埚中,设定熔炼炉温度为780℃后开始加热,并撒上镁合金熔炼覆盖剂,待坩埚中的合金熔化后加入Mg-Er中间合金,经搅拌,撇去Mg-Zn-Er合金液表面浮渣及覆盖剂后浇铸于金属模中。本发明的合金具有较高的高温强度和抗蠕变性能。
