The bimetal composite materials generally have superior comprehensive properties which are extremely difficult to achieve for single metal materials.Comparing to other bimetal bonding processes

the solid-liquid bimetal compound casting process has been widely used in modern industry with the advantages of good interface bonding quality

high production efficiency and wide range of applicable alloys

etc.The research progress and development status on the process and formation mechanism of solid-liquid bimetal compound casting was reviewed at home and abroad.Main forming processes subdivided within the solid-liquid bimetal compound casting and the corresponding applications were described.Meanwhile

the major factors affecting the bonding quality of the bimetal interface were analyzed.Research concerns and mainstream opinions were summarized on the microstructure and properties at the bonding interface of the solid-liquid bimetals.Finally

the shortcomings existed in the current research on solid-liquid bimetal compound casting and development directions forwards were pointed out.
