| Abstract: | The variation of the intensity of MAE with stress in type 16Mn steel is investigated. Some parameters for the determination of the stress with MAE are suggested. An expression for the relationship between the amplitude of MAE (up) and applied stress, This expression provides a basis for the detection of the residualstress in ferromagnetic materials. The residual stress in the welded plate has been measured. |
