摘要	The liquid structure and melt treatment of M963 Ni base superalloy have been studied by using high temperature X-ray diffraction. The results show that there exist Ni3Al-like cluster and residual MC carbide in the alloy melt superheated at 1520 degrees C, and the liquid structure of the M963 superalloy has a close relationship to the thermal history of the alloy melt. Both the rupture life and elongation of M963 superalloy at 975 degrees C under 225 MPa are all prolonged obviously by melt treatment at 1550-1650 degrees C. The commercial MgO crucible is unsuitable for high temperature treatment of melt at 1850 degrees C, but by using a new developed crucible such treatment can carry out and can obviously increase the rupture property of the recycled M963 superalloy at 975 degrees C and 225 MPa.
