摘　　要：以自主研发的Al-Fe-Mn铝合金板材和2个不同批次的进口电池壳盖板用铝板为试验材料,采用单向拉伸试验和杯突试验测定了3种铝合金板的塑性应变比、凸耳参数以及杯突值。通过电子背散射衍射技术测定并计算了铝合金板的取向分布函数和主要织构组分的体积分数,研究了织构对铝板冲压性能的影响。结果表明:自主研发DQAl铝板虽然与进口铝合金板织构组分不同,但通过优化织构组分,即增加Cube织构组分、减少Copper织构组分,以及将Q织构组分与较高■值的R和S织构组分组合,很好地改善了DQAl铝板的各向异性,由此获得了与进口电池壳盖板用铝板十分接近的成形性能。Taking self-developed Al-Fe-Mn aluminum alloy sheet and two different batches of imported aluminum sheets for battery shell cover as the test materials, the plastic strain ratio, earing parameter and cupping value of the three aluminum alloy sheets were measured by uniaxial tensile test and Erichsen test. The orientation distribution function and the volume fraction of the main texture components were measured and calculated by electron back scatter diffraction technique, and the effect of texture on the stamping ability of aluminum alloy sheet was studied. The results indicated that although the texture components of the self-developed DQAl aluminum sheet were different from those of the imported aluminum alloy sheet, the anisotropy of the DQAl aluminum sheet was well improved by optimizing the texture components, i.e, increasing the Cube texture component, decreasing the Copper texture component, and combining the Q texture and the R, S texture with higher ■, thus, its formability being close to that of the imported aluminum sheet for battery shell cover.
