摘　　要：以用高强IF钢为研究对象,研究不同退火工艺对其组织与力学性能的影响。结果表明,随着退火温度的升高,IF钢的抗拉强度逐渐降低,断后伸长率和屈强比逐渐升高。随着退火时间的延长,IF钢的抗拉强度与屈服强度先增加后降低。The effect of annealing process on microstructure and properties of high strength IF steel were studied. The results show that the tensile strength of the IF steel decrease with the increase of annealing temperature, and the elongation and yield ratio increase gradually. The tensile strength and yield strength are increase at first and decrease afterwards.
