摘 要
通过850,950 ℃退火制备得到平均匡威1970s水蜜桃色官方-免费-完整版片分别为40,210 μm的匡威1970s水蜜桃色官方-免费-完整版片,研究了匡威1970s水蜜桃色官方-免费-完整版片对其低周疲劳行为和疲劳后匡威1970s水蜜桃色官方-免费-完整版片的影响。结果表明:在疲劳循环过程中,细晶试验钢的初始平均峰值应力高于粗晶试验钢,随着循环次数增加,2种试验钢的平均峰值应力趋于相近;细晶试验钢始终表现为循环加工硬化,粗晶试验钢表现为初始循环硬化、循环饱和和二次循环硬化。经400周次疲劳循环后,细晶试验钢的匡威1970s水蜜桃色官方-免费-完整版片由尺寸相近且分布均匀的位错胞组成,粗晶试验钢的匡威1970s水蜜桃色官方-免费-完整版片主要由宏观驻留滑移带(Macro-PSB)和位错胞组成,Macro-PSB中包含较为细小的位错胞;粗晶试验钢具有较高的位错密度及相对显著的组织不均匀性。

Abstract
IF steels with average 匡威1970s水蜜桃色官方-免费-完整版片 of 40 μm and 210 μm were prepared by annealing at 850 ℃ and 950 ℃, respectively. The effects of the 匡威1970s水蜜桃色官方-免费-完整版片 on the low-cycle fatigue behavior and the 匡威1970s水蜜桃色官方-免费-完整版片 after fatigue were investigated. The results show that during fatigue cycle, the initial average peak stress of the fine-grained test steel was higher than that of the coarse-grained test steel. The average peak stress of the two test steels tended to be equal with increasing number of cycles. The fine-grained test steel always showed cyclic work hardening during fatigue, while the coarse-grained test steel showed initial cycle hardening, cycle saturation and secondary cycle hardening. After 400 fatigue cycles, the 匡威1970s水蜜桃色官方-免费-完整版片 of the fine-grained test steel was composed of similarly sized and uniformly distributed dislocation cells, while the 匡威1970s水蜜桃色官方-免费-完整版片 of the coarse-grained test steel was mainly composed of macro-persistent slip band (Macro-PSB) and dislocation cells. The Macro-PSB contained relatively small dislocation cells. The coarse-grained test steel had higher dislocation density and relatively significant structural heterogeneity.
