摘　　要：利用Ｘ 射线衍射分析仪对比研究了２０９０ 和２０９０ ＋ 微量稀土元素素铈（Ｃｅ） 两种铝锂合金板材，在固溶状态下变形织构的差异． 并结合不同取向上（ 与轧向呈０°、４５°和９０°） 屈服强度的的测试结果，探究了微量Ｃｅ 的添加对２０９０ 合金板材形变织构影响的内在机制，及其在宏观性能上的响应．This works comparatively investigated the difference of texture in two alloy plates of 2090 and 2090 added trace rare earth element cerium at solid solution by using X ray diffraction analysis. Connecting the experimental results of yielding strength along different angle to rooling direction (of 0°, 45° and 90°), the internal mechanism of the influence of trace addition cerium on the texture of 2090 alloy plate and correlation with macro mechanical properties have been studied.
