Zr对Al-Li合金热轧板材的再结晶温度、各向异性和织构的影响

Effect of zirconium on the recrystallization, anisotropy and texture in Al-Li alloys

研究了Zr元素对Al Li二元合金热轧板内织构、各向异性以及再结晶温度的影响 ,发现微量的Zr(0 .0 8% )即可起到抑制再结晶的作用 ,Zr含量增加 (0 .14% )时 ,热轧板材的组织细化 ,合金的强塑性提高。从实验结果还可以看出 ,Al Li二元合金的各向异性除受材料内部的晶体学织构影响外 ,其他因素 (如合金内第二相粒子的特性 )

The recrystallization, anisotropy and texture of Al-Li(-Zr) alloys were studied. The element zr can retard the recrystallization processing and refine grains. It can be concluded that the mechanical properties anisotropy of Al-Li(-Zr) alloys is affected not only by crystalline textures but also by other aspects such as characteristics of the second phase particles in the matrix.
