本文研究了16Mn钢的低温疲劳裂纹起始,并力图提出可定量预测低碳低合金钢低温疲劳裂纹起始寿命的新方法。根据本文的研究结果,低温疲劳裂纹起始寿命可由拉伸性能进行估算,并且不需要任何低温疲劳试验和附加的经验修正。
In this paper, the onset of low temperature fatigue cracking of 16Mn steel was studied and a new method of predicting the onset fatigue life of low-carbon low-alloy fatigue at low temperature was proposed. Based on the results of this study, the onset fatigue life at low temperature can be estimated from the tensile properties and does not require any low-temperature fatigue test and additional empirical corrections.
