| Abstract: | Squeeze casting is a technology with short route, high efficiency, precise forming which possesses the features of casting and plastic processing. It is applied to produce high performance and high precision parts which are widely used in machinery, automobile, household, aviation, aerospace and defense. In this paper, the characteristics and history of squeeze casting are introduced briefly. Then the effect of applied pressure on the metallurgica｜ and mechanical behavior of liquid metal is analyzed. Furthermore, the research progress in the developed materials, process optimization, forming of parts, numerical simulation and equipment of squeeze casting is summarized comprehensively. Finally, the future trends of squeeze casting are presented. |
