| 摘 要： | 非调质钢常用来代替调质钢制造用于疲劳设计的运动部件,因而改善其疲劳性能十分重要.对于铁素体一珠光体型非调质钢,由于存在软相铁素体,其疲劳裂纹基本上萌生于试样表面的铁素体/珠光体边界,并优先沿着该边界扩展.因此,强化铁素体、改善铁素体的分布状态和组织细化是改善其疲劳性能的关键.研究结果证实,具有粗大网状铁素体一珠光体组织...

| Abstract: | It is demanded to improve the fatigue properties of medium-carbon microalloyed forging steels which are increasingly used to replace conventional quenched and tempered(QT) medium-carbon steels for the manufacture of fatigue design components.For ferrite-pearlite steel,owing to the existence of soft phase of ferrite,it was revealed that fatigue crack preferentially initiated and propagated along the ferrite/pearlite boundary in the early stage of fatigue crack propagation.Therefore,the fatigue property of fe... |
