稀土Nd对α相Mg-Li合金热挤压织构的影响崔崇亮1,朱天龙1,孙俭峰1,2,巫瑞智1,张密林11. 哈尔滨工程大学超轻材料与表面技术教育部重点实验室2. 黑龙江科技学院摘 要:研究了挤压态Mg-5Li-3Al-2Zn-XNd(X=0,0.4,2.0,质量分数,%)合金的显微组织及其织构演变情况.结果表明,Nd的加入有利于合金在变形过程中启动非基面滑移.当Nd添加量为2.0%时,(0002)极图中显示出了Mg合金中罕见的非基面织构类型(ND向TD右侧偏转约30°).非基面滑移系的出现一方面与加入Nd后合金的c/a值进一步减小有关,又与大量弥散分布在合金中的Al-RE相对基面织构的弱化有关.另外,由于稀土元素的加入对Mg合金的层错能的改变也有一定作用.关键词:稀土;镁锂合金;挤压;极图;......
. According to the results of ENGLER et al [1], a high recrystallization rate has been observed in Al-Mg alloy due to addition of element Mg. However, recrystallization during self-annealing... in other works [15-16]. One possible explanation is that the cross slip is obstructed because of the greatly reduced stacking fault energy in aluminum alloy 5182 due to the much high content of Mg element......
