采用光学金相和电子金相分析方法,对大锻轴的表面裂纹性质和产生原因进行了分析。结果表明,大锻轴表面裂纹为锻造裂纹。锻造时加热温度过高或加热时间过长是其产生的主要原因。
Using optical metallography and electronic metallographic analysis, the surface crack characters and causes of the forging shaft were analyzed. The results show that the surface of large forging shaft crack forging cracks. Forging the heating temperature is too high or heating time is the main reason for its generation.
