摘要
通过电阻法研究了二元Ａｌ－２．０Ｌｉ（质量百分比）合金在１００℃、１９０℃时效时的电阻率随时效时间的变化。研究结果表明，二元Ａｌ－Ｌｉ合金固溶体分解过程中首先发现了短程有序化，然后通过均匀有序化形成δ’相．最后形成δ相。
Phase transformation process of Al-2.0Li(wt%) alloy was investigated by resistance measurement at 100℃ and 190℃. The results indicated that a short-range ordering process took place before the forming of the long-range ordering δ 'phase which was developed by a homogeneous ordering in the decomposition of Al-Li alloy, and δ phase was formed after δ 'phase.
