By using ψ0 oscillation method with CrKβ γ(311) diffraction, the X-ray stress measurement was made on five specimens, which were obtained by water toughening and various plastic working treatments (tensile pre-strain, hammered and explosive hardening) from Hadfield's high manganese austenitic steel, and their mechanical elastic constants, X-ray elastic constants and the accuracy of measurement were examined.<br>The results obtained are as follows:<br>(1) The mechanical elastic constant for 13% Mn austenitic steel after water toughening was 18900kg/mm2. This value gradually decreased with increasing tensile pre-strain. But it changed little when the specimen was treated by hammered or explosive hardening.<br>(2) The K-value (KX=-37.26kg/mm2/deg) of austenitic steel adopted in the standard method of X-ray stress measurement is considered suitable for the X-ray stress measurement of 13% Mn austenitic steel which has not been subjected to severe plastic deformation.<br>(3) The error in stress measurement Δσ in the X-ray stress measurement of high manganese austenitic steel becomes larger, depending more on the statistical fluctuation parameter, than that of ferritic steel.
