中文摘要：研究了罩式退火保温温度和保温时间对高强IF钢性能的影响。 结果表明，退火保温温度是影响高强IF钢性能的主要因素，最高退火保温温度应不高于750 ℃； 而退火保温时间对钢板力学性能的影响不大，退火保温时间以2 h为宜。
英文摘要：The effects of annealing temperature and holding time on the properties of IF steel were studied. The results show that the annealing temperature is a main effect factor on the properties of high-strength IF steel, and the highest temperature should not be above 750 ℃; while, the annealing time has little effect on the properties of finished products, and the advisable annealing time is 2 h.
