摘　　要：用三维取向分布函数（ＯＤＦ）分析技术研究了武钢微碳深冲钢板（０３Ａｌ）在工业生产各主要工序中的织构特征与演变、力学性能和成型性能。结果表明：①热轧、冷轧与退火织构类型与铝镇静深冲钢板（０８Ａｌ）相类似，但冷轧和退火后，有利织构明显增强；②武钢通过对碳含量在０．０１％～０．０２％的微碳深冲钢板进行成分设定和选定工艺参数，可生产出基本成型性能ｎ＝０．１９３～０．２４１、ｒ＝１．６８４～１．９３９的高品质的深冲钢板，其技术指标达到和超过了日本ＳＰＣＥＮ深冲钢板的水平。The texture and its evolution of lowcarbon deep drawing steel sheet at main steps in production such as hotrolling,coldrolling and annealing have been investigated by means of ODFThe mechanical properties and formability of steel sheets were measuredResults show that ①the texture of lowcarbon deep drawing steel is similar to that of aluminiumkilled steel,but favorable texture components become more strong after rolling and annealing;②with optimal chemical composition and processing parameters the lowcarbon deep drawing steel with excellent formability of n=0193～0241,r=1684～1939 can be produced,which are better than SPCEN grade made in Japan
