After heat treatment of the tooth wheel axle,the crosswise break happened during the adjustment process. For analysising the break reason,the macroscopic,the microscopic examination and the SEM fracture analysis technology were conducted. The result analysis were showed that terminste temperature higher of the forge heats up the hyperpyrexia to produce the naphthalene shapefracture,finally caused breaks when adjusting.
