| Abstract: | Based on the theory of magetic acoustic emission (MAE), the stress in an annealed rail is calibrated with a special-made magnetizer, and the relationship between the calibrated stress and MAE strength is obtained by area method. With the calibration curve the residual stress in a U74 60 kg/m new rail is measured. |
