| 摘 要： | 采用正交试验法研究了冷轧压下量(65%～80%)和退火温度(660～780℃)对Ti-IF钢(/%:0.02C、0.012Si、0.10Mn、0.013P、0.011S、0.064Ti、0.0020N)组织、力学和成形性能的影响。试验结果表明,≥700℃退火Ti-IF钢再结晶基本完成,当压下量75%700℃退火时,该钢具有较好的综合性能:屈服强度120 MPa,屈强比0.38,应变硬化指数n值0.25,塑性应变比r值1.65。

| Abstract: | Influence of cold rolling reduction (65%-80% ) and annealing temperature (660-780 ℃ ) on structure, mechanical properties and formability of a Ti-IF steel (/% : 0.02C, 0.012Si, 0.10Mn, 0.013P, 0.011S, 0.064Ti, 0.0020N) has been studied by orthogonal experimental method. Test results show that with annealing at ≥ 700 ℃ the recrystallization of Ti-IF steel is basically completed t with reduction 75% and annealing at 700 °C the steel has better comprehensive properties i. e. yield strength 120 MPa, yield-tensile ratio 0.38, strain-hardening exponent n value 0.25 and plastic strain ratio r value 1.65. |
