| 摘 要： | 报道了含1.2%Al-0.1%C-Mn-Si冷轧TRIP600钢带的研究开发结果,通过合金设计、冶炼、热轧、冷轧和热处理在实验室成功地制备了TRIP600钢带,其屈服强度为390~420 MPa、抗拉强度650~700 MPa,伸长率30.5%~37.5%,强塑积21000~26000 MPa.%。作为热处理工艺设计的基础,通过Thermo-Calc软件计算了试验钢的相图、相组成、贝氏体转变TTT曲线和T0温度线。含质量分数为1.20%铝的冷轧TRIP600的成分设计和工艺参数可以作为工业试生产TRIP600的基础。

| Abstract: | TRIP-600 steel containing 1.2%Al was reserched on a laboratory scale.The phase diagrams,TTT curves and T0 lines of bainite formation in the steel were calculated with Thermo-Calc.The TRIP600 strips were successfully prepared through a designed process including steel-making,hot and cold rolling as well as heat treatments.Tensile strength 650-700 MPa,yield strength 390-420 MPa and total elongation 30.5%-37.5% is obtained for the steel strips.The chemical compositions and processing parameters can be referred... |
