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．
The difference of deformation textures of 2090 and 2090 + rare earth cerium (Ce) two Al-Li alloy plates was studied by means of X-ray diffraction analyzer. Based on the results of the test of yield strength at different orientations (0 °, 45 ° and 90 ° with respect to the rolling direction), the intrinsic mechanism of the effect of addition of trace Ce on the texturing of 2090 alloy sheet was investigated and its macroscopic properties the response to.
