Abstract: The effect of trace Mg in Ni-base GH220 superalloy on the degree of long range order (DLRO) of γ′-phase has been studied through a contrast between the integral intensities of a basic line (220) and a superstructural line (100) by using an X-ray diffraction technique. The experimental results show that the addition of trace Mg to the alloy will increase greatly the DLRO and the anti-phase domain boundary energy of γ′-phase. As a result, the resistance provided by γ′-phase to the dislocation movement can be increased. This may be considered one of the important strengthening mechanisms of superalloys.
