摘要
对主轴表面裂纹的形貌特征和材质的化学成分进行分析 ,金相检验发现裂纹两侧有不同程度的脱碳情况 ,可以判定表面裂纹的产生是在主轴锻造和热处理之前 。
According to the appearance and features of the surface cracks,the analysis of chemical constitution of the material and the decarburization of the different degrees on the two sides of cracks found during metallographic examination,it may be judged that the cracks take place before forging and heat treating, having relation to the poor rolling of the shaft blank
