非调质45VS钢疲劳性能及裂纹扩展规律研究
Fatigue Properties and Crack Propagation of Non-treatable Steel 45 VS
【摘要】 本文测定了非调质45VS钢和40钢汽车发动机连杆疲劳曲线,并利用电子显微镜观察了裂纹扩展规律及位错结构,结果表明,45VS连杆在低载荷区具有较高的循环次数和疲劳强度。
【Abstract】 Fatigue curves of automobile engine connecting rod of non-treatable steel 45 VS and steel 40 were plotted. Crack propagation and dislocation structure were investigated by means of EM. It was showed that 45VS had long life and good fatigue strength in the range low load.
