【Abstract】 Based on the difference of specific volume of martensite and pearlite,a relationship between the hardened depth and the diameter change of workpiece before and after induction hardening was built.It shows that a simple non-destructive method to measure the hardened depth is feasible in theory,and it was also proved in experiments.更多还原
