Abstract:Squeeze casting is refined as a process in which liquid metal fills a die cavity and solidifies under pressure. High pressure leads to a refinement of grain size, change of microstructure morphology and adjustment and control of cast defects. Therefore, it is a precise, near-net and green forming technology integrating the advantages of casting and forging technology. At present, aluminum alloy is one of the main materials used in squeeze casting. This paper review and analyze the development status about aluminum alloy squeeze casting technology at home and abroad from five aspects, such as heat and mass transfer theory, numerical simulation technology, the development of aluminum alloy squeeze casting equipment,?aluminum alloy squeeze casting technology and outlook of the development direction of aluminum alloy squeeze casting. It aims to provide some reference to the development of aluminum alloy squeeze casting technology and further popularization and application.
Key words: aluminum alloy; squeeze casting; numerical simulation; squeeze casting equipment
