| Abstract: | Cracking and distortion are the common defects in heat treatment for steel parts which will be scraped if the defects are grave.Taking the discal part of 35 steel and the bevel gear of 20CrMnTi steel of automobile rear axle for example,the causes for cracking and distortion of the parts during the quenching were analyzed as viewed from raw material quality,heat treatment process,quenchant,workholder and so on.The measures to protect parts from cracking and distortion were also put forward. |
