以CSP工艺在不同卷取温度下生产的含B((40~60)×10-6,质量分数)和无B 08A1的冷轧基板为实验材料,采用不同的冷轧总变形量进行冷轧退火后,通过单向拉伸实验对两种钢的基本成形性能指标(r值、n值)和力学性能指标(屈服强度、抗拉强度、伸长率)进行测定,并对卷取温度为620 ℃、冷轧总压下量为75%的两种钢的退火试样进行织构测试和EBSD分析.对比分析发现,卷取温度、冷轧压下量对退火后的无B 08Al钢和含B 08A1钢成形性能及力学性能的影响显著,ODF和EBSD分析表明,含B钢中的γ纤维织构组分要低于无B钢,而旋转立方织构({001}《110》)和Goss织构({011}《100》)明显高于无B钢.
