. Key words: magnesium alloy; rare-earth element; creep mechanism 镁合金是工业应用中最轻的金属结构材料,在汽车,航空航天等领域有着巨大的应用前景,被认为是目前最具发展前途的金属材料.然而,常规镁合金的高温力学性能普遍较差.开发新型高强度耐热镁合金已成为国内外镁合金研究的重点方向之一[1]. 稀土元素由于具有独特的核外电子结构,作为一种重要...): 1587-1591.LI Jie-hua, JIE Wan-qi, YANG Guang-yu.

energy[2-3], magnesium alloys have poor plastic deformation property. This is why the cast magnesium alloys are developed prior to wrought magnesium alloys. It has been reported that rare earth elements could remarkably improve the mechanical ability of magnesium at room and high temperatures[4]. So, magnesium alloys with rare earth elements attract much interest. Homogenization treatment is very......
