Bimetallic compound casting combines 2 metal materials with different compositions and properties into a single integral casting, meeting the performance requirements at different parts of the components that are difficult to achieve with a single metal material, and achieving automotive lightweight. This paper reviews liquid-solid bimetallic compound casting process, analyzes the bonding mechanisms and formation conditions of bimetallic interfaces, and summarizes the interface microstructure and performance control technology such as surface treatment, insert preheating, adding interlayers and application of physical fields, it also presents the typical applications and manufacturing processes of aluminum/cast iron, aluminum/steel, aluminum/magnesium and steel/cast iron bimetallic compound casting in automotive lightweight manufacturing. The paper finally presents the research direction and development prospect of bimetallic compound casting, providing a valuable reference for the research and its application in automotive manufacturing.
