摘要

本文采用XRD、EBSD和拉伸实验,结合晶体塑性模拟,研究冷轧变形量和热处理对7085铝合金织构组分和塑性应变比r的影响,分析5种理想织构对平均塑性应变比和平面各向异性指数|Δr|的影响。结果表明：冷轧过程中变形量从50%增大至80%,S织构体积分数增幅最大(10.9%),Copper织构增幅最小(2.9%),再结晶织构变化不大。热处理后,合金的Brass、S和Copper织构均减弱,且变形量为80%时S织构减幅最大(15.9%),Copper织构减幅最小(2.4%);Cube织构有所增加,且变形量越大,增幅越显著;Goss织构变化不明显。冷轧态合金的|Δr|值大于时效态的;随冷轧变形量增大,冷轧态合金的值逐渐增大,而时效态的值则逐渐减小,同时|Δr|值均逐渐增大。轧制织构Δr<0,而再结晶织构Δr>0。Goss织构主要提供90°方向上的抗变形能力,Cube织构在3个方向上的r值差异较小。

Abstract

The effects of cold rolling deformation and heat treatment on texture composition and plastic strain ratio r of 7085 aluminum alloy were investigated by XRD, EBSD, and tensile experiments combined with crystal plasticity simulation. The effects of five ideal textures on average plastic strain ratio and planar anisotropy index |Δr| were analyzed. The results show that when the deformation increases from 50% to 80% during cold rolling, the volume fraction of S texture increases the most (10.9%), the volume fraction of Copper texture increases the least (2.9%), and the recrystallization texture changes little. After heat treatment, the Brass, S, and Copper textures of the alloys are weakened, when the deformation amount is 80%, the S texture decreases the most (15.9%) and the Copper texture decreases the least (2.4%); the Cube texture increases, and the larger the deformation is, the more significant the increase is; the Goss texture change is not obvious. The |Δr| value of cold-rolled alloy is higher than that of aged alloy; with the increase of cold rolling deformation, the value of cold rolled alloy increases gradually, the value of aged alloy decreases gradually, and the |Δr| value increases gradually. Rolled texture Δr<0 while recrystallization texture Δr>0. The Goss texture mainly provides resistance to deformation in the 90° direction, while the Cube texture has little difference in r value in the three directions.

Key words： 7085 aluminum alloy; cold rolling; heat treatment; texture; plastic strain ratio; crystal plasticity
