摘要(Abstract)：

对工业生产的No.1微碳BH钢和No.2微碳BH钢热轧板、冷轧板和退火板的工艺和组织性能进行研究。结果表明,No.1和No.2微碳BH钢的γ织构组分在{111}<110>附近分别达到了最大值12.046和10.549。No.2微碳BH钢退火板平均晶粒尺寸均小于No.1微碳BH钢,细晶强化效果使得其强度略高。No.2微碳BH钢退火板铁素体晶界处和晶粒内均存在游离渗碳体,晶界处珠光体片层较少,No.1微碳BH钢退火板铁素体晶界处存在片层状珠光体和块状渗碳体,更多珠光体片层结构也使其强度较低。No.2微碳BH钢中较高含量P、Cr、Cu元素固溶在基体中引起固溶强化,碳氮化物析出的弥散强化作用,均弥补了C含量较低引起的强度下降。
