Abstract According to the characteristics of superplastic micro-extrusion, micro-extrusion finite element model is built. The infl uences of size effect are simulated and analyzed by extrusion pressure, effective stress distribution and the changes of fl ow grid, on the basis of size effect of parts at micro dimension. Through this study, the necessary information and guides are provided for the further research of extrusion of micro-parts.
