检测了宝钢两组IF钢板与轧向夹角分别为0°,15°,30°,45°,60°,75°,90°的R值以及板材的织构.计算了板材的{001}<110>、{112}<110>、{110}<001>、{111}<110>和{111}<112>织构组分的体积量,利用Sachs模型分析了{112}<110>和{110}<001>织构对轧板上不同方向的R值的影响.结果表明,IF钢板板面不同方向上存在R值的显著起伏.计算与实测结果表明,{112}<110>和{110}<001>织构是造成板材R(θ)值起伏的重要因素.在增大{111}面织构并减小{100}面织构的同时,合理控制{112}<110>和{110}<001>织构组分有可能使深冲压钢板获得高R值的同时明显降低R值的起伏.
