摘要	The effect of melt superheating treatment on the microstructure and stress rupture properties of M963 superalloy under the condition of 1248 K/225 MPa has been investigated. The results show that with the increase of melt superheating temperature, the primary carbide MC in the as-cast condition becomes finer and more homogeneous gradually, and both the rupture life and elongation increase greatly. However, when the melt superheating temperature reaches 2023 K, the stress rupture performance of the superalloy is deteriorated due to the increase of gas content and microporosity. Both the rupture life and elongation of as-cast M963 superalloy under 1923 K melt superheating treatment and 1248 K/225 MPa can be doubled and even more.
