【Abstract】 The influence of MAE strength which is produced from different stress states of ferro-magnetic materials has been studied in this paper.We have designed a special magnetizer which can be used on ferro-magnetic material. Therefore, the measurement method can be brought in practice for the residual stress in workpiece by the local magnetization, We also have found the relationship between the magnetic depth of workpiece and the current strength of magnetizer.更多还原
