Abstract: Superalloys are widely used in aerospace,energy,automotive and other critical fields due to their excellent mechanical properties and corrosion resistance.However,the melting of superalloys imposes extremely high requirements on the performance of crucible materials,which need to possess excellent properties such as high thermal shock resistance and outstanding chemical stability.The main melting methods of superalloys and the performance requirements for crucible materials were described,various common oxide and non-oxide crucible materials were introduced,performance optimization strategies for crucibles were especially discussed,including material composition modification,microstructure adjustment,and surface coating introduction.It is expected to provide a reference for the design and development of new high-performance crucible materials.

Key words: superalloys, melting, crucible materials, performance optimization
