摘要
采用热/力压缩模拟实验研究了3种镁-稀土合金在不同变形条件下高温塑性变形行为。结果表明,在相同的应变速率、变形温度条件下,含Ce的合金流变应力小于含Nd的合金和含Nd和Y的合金。从热加工难易程度的角度考虑,含Ce的合金更适合挤压成型。
The elevated temperature plastic deformation was studied by thermomechanical processes for three kinds of Mg-RE alloys in different temperature and different strain rate. The results show that the flow stress of 1# alloy containing Ce is lower than that of 2# alloy containing Nd, and 3# alloy containing Nd and Y at same temperature and same strain rate. The 1# alloy containing Ce is more suitable for extrusion forming from thermal deformation angle.
