调整螺母在调质处理后探伤时发现有裂纹,采用宏观检验、化学成分分析、金相检验等
方法对开裂的调整螺母进行了分析.结果表明:该批调整螺母开裂是由于明显的带状偏析和较多的夹杂物引起的淬火裂纹,同时由于回火温度过高,使得裂纹两侧脱碳出现网状铁素体.
Adjusting nut at after quenching and tempering treatment inspection found that crack, by macroscopic inspection, chemical composition analysis, metallographic examinationMethod of cracking of the adjusting nut are analyzed. The results showed that: the number of the adjusting nut cracking due to apparent banding segregation and more inclusions caused by quenching crack, at the same time as the tempering temperature is too high, the crack appears on both sides of the reticular ferrite decarbonization.
