含铈、镧的AE系耐热压铸镁合金
摘要：
本发明涉及含铈、镧的AE系耐热压铸镁合金，组成成分及其重量百分比为：Al：3％～5％，Ce：0.4％～2.6％，La：0.4％～2.6％，Mn：0.2％～0.6％，余量为镁。所用原材料铈镧混合稀土是将普通富铈混合稀土中价值高、市场好的Nd、Pr分离出去剩余的廉价的、大量积压的铈镧混合稀土。本发明的室温和高温力学性能优于AE44和AZ91合金，并且200℃，70MPa条件下最小蠕变速率为1.82×10－9s－1，100小时蠕变伸长率为0.17％，均优于AE44合金。
摘要（英）：

The invention relates to an AE series heat resistant casting magnesium alloy containing cerium and lanthanum, which comprises and has the weight percentage of each element of: Al:3%-5%, Ce:0.4%-2.6%, La:0.4%-2.6%, Mn:0.2%-0.6%, the rest being magnesium. The lanthanum cerium mischmetal used is produced by separating the Nd, Pr which is more valuable and selling from ordinary cerium rich mischmetal which leaves the cheap and abundant cerium lanthanum mischmetal. The invention has better mechanical performance in both normal and high temperature than AE44 and AZ91alloy, and the minimum creep rate under 200 DEG C, 70MPa is 1.82 multiplied by10-9s-1, 100 hour creeping elongation rate is 0.17%, all being better than an AE44 alloy.
