AbstractUsing high temperature X-ray diffraction, the liquid structure and the relationship between the liquid structure and thermal history of cast nickel base superalloy M963 have been investigated. The results show that there are two distinct pre-peaks at the part of the low scattering vector in the 1773 K X-ray diffraction pattern of the alloy melt superheated at 1793 K. These pre-peaks correspond to the 100 superstructure peak of gamma' phase and 110 peak of MC carbide in the solid alloy, respectively, which indicates that there are two kinds of order clusters, Ni3Al and MC carbide, in the alloy melt. When the alloy melt is superheated to 1873 K, the pre-peaks in the X-ray diffraction pattern of melt at 1853 K disappear, and only the pre-peak corresponding to the 100 superstructure peak of gamma' phase is found again with decreasing the temperature. It is suggested that there exists a close relationship between the liquid structure and thermal history of the cast superalloy.
