Al-Li合金板 <111> 织构的形成及晶体空间取向分布特征

Formation of <111> Texture and Characteristics of Crystallographic Orientation in Al-Li Alloy Sheets

用ODF方法研究了Al Li合金形变热处理的织构、织构特征及其变化规律。实验在这种fcc结构的Al Li合金板中发现了{111}//ND纤维织构,最大f(g)大于3。同时,对其形成机制进行了分析讨论。

The textures and their evolution law of AlLi alloy after deformation and heat treatment are studied by means of ODF.During the experiment,{111}//ND fiberous texture was formed in fcc AlLi alloy sheet with f(g)>3.Other related mechanisms are also discussed.
