摘要:

研究了50CrVA高强弹簧钢在不同热处理状态下(淬火+中温回火和退火)的超高周疲劳破坏行为及其裂纹萌生机理。结果表明, 50CrVA高强弹簧钢在10⁷~10⁹循环周次内发生疲劳破坏, 两种热处理状态的S-N曲线下降形态不同, 均未出现疲劳极限。热处理工艺改变50CrVA的微观组织, 从而影响超高周疲劳阶段(寿命>10⁷周次)的疲劳破坏损伤机制: 经淬火+中温回火处理材料破坏多起源于内部夹杂物, 夹杂物周围存在的应力场与溶质原子发生弹性交互作用, 吸引间隙原子向其周边扩散、富集, 使间隙原子富集区材料性能下降, 导致裂纹在内部夹杂物处萌生; 退火热处理后材料微观组织对间隙原子向材料内部夹杂物扩散起到阻碍作用, 所以超高周疲劳裂纹易于在材料表面萌生。

Abstract：

Ultrahigh cycle fatigue behavior of 50CrVA spring steel, which was treated successively byquenched, tempered (QT) and annealed (AD) processes, was investigated by ultrasonic fatigue testingtechnique. The results showed that in ultra-long life regimes (10⁷~10⁹ cycles) the fatigue damage occurred, and the S-N curves displayed different forms. Different heat treatment process could induce different microstructure of the steel; there with regulate the relevant ultrahigh cycle fatigue damage mechanism. In QT state, fatigue cracks generally originated from inner oxide inclusions. It was probably due to that elastic interaction between microcrack tip stresses and interstitial atoms, which enable carbon atoms to be enriched around the particles, causing the degradation of performance of the region rich in carbon and initiation of fatigue cracks. In AD state, the enrichment of interstitial atoms was difficult due to that the special microstructure inhibited the diffusion of atoms approaching to impurity particles so that the cracks were prone to initiate from the steel surface.
