Abstract:The metallurgical quality of superalloy is closely related to the comprehensive performance of materials. Homogenized smelting has become an important method to improve the distribution uniformity of alloy composition, structure and the second phase, as well as the mechanical properties of the alloy. Based on the previous studies, the influencing factors of homogenized smelting and the effective measures to improve the homogenization level of nickel-based superalloy were reviewed. The effects of solidification segregation, element burning loss and homogenization treatment on the homogenized smelting of nickel-based superalloy were discussed in order to provide a reference for improving the homogenized smelting level of nickel-based superalloy and optimizing the preparation process.
