摘要(Abstract)：

利用等温退火法测定了3种不同Ti含量热轧带钢在冷轧后的退火再结晶温度，通过光学显微镜、透射电镜、显微硬度计和电子万能实验机等研究了Ti含量和退火温度对冷轧钢显微组织和力学性能的影响。结果表明：随着Ti含量的增加，纳米级含Ti析出物对晶界的钉扎作用增强，导致冷轧钢的硬度升高，同时其再结晶开始温度也随之上升，C-Mn钢的再结晶温度为540～560℃,0.05%Ti钢为620～640℃,而0.08%Ti钢则进一步提高至660～680℃;TiC析出物的形成有效抑制了再结晶过程，使得再结晶发生时间延迟，并促使晶粒尺寸细化；随着钢中Ti含量的增加，相同退火温度下冷轧钢的屈服强度呈现上升趋势，而伸长率则有所下降；特别地，当0.08Ti钢在640℃左右进行退火处理时，其伸长率可达到约10%,同时保持较高的屈服强度水平(850 MPa左右)。
