【Abstract】 A systematic review for the research of microforming processes (forming of micropart and microstructured components) was presented. The main considerations include the following cases: firstly,the microforming-technics system and the test results in the micro-punching,micro-extrusion,micro-deep-drawing and superplastical microforming,secondly,the phenomena and the mechanism of micro-size effect in the microforming,and thirdly,a review on the developed or developing micro-size constitutive equation .In the end,related equipment of microforming in the world was reviewed. All these results show the developing trends and inherent economic potential on microforming in the future.更多还原
