摘　　要：采用单轴拉伸力学性能测试结合EBSD(电子背散射衍射技术)分析,探讨了冷变形量对6016铝合金r值(塑性应变比)的影响。结果表明:随着冷变形量增加,固溶淬火后6016铝合金薄板单轴拉伸r45°增加;6016铝合金薄板淬火后主要有立方织构和R织构,并且不同冷轧工艺会导致淬火后形成不相同的织构组分,从而使得材料表现出不同程度的各向异性。The effect of cold deformation on 6016 aluminum alloy r value(plastic strain ratio) was studied by uniaxial tensile mechanical property test combined with EBSD(electron back-scattered diffraction) analysis. The results show that after solid solution quenching, the uniaxial tensile r 45°of 6016 aluminum alloy sheet increases with the increase of cold deformation.6016 aluminum alloy sheet has cubic texture and R texture after quenching. And different cold rolling processes will lead to different texture components after quenching, so that the materials show different degrees of anisotropy.
