摘　　要：采用模糊层次分析法,对影响半固态微挤压件尺寸精度的影响因素,如挤压力、回弹、模具高温热膨胀情况及材料固相率等进行分析排序,并给出相应的权重大小。其结果对半固态微挤压尺寸精度的控制具有实际意义。By using fuzzy analytic hierarchy process（FAHP）, the influence degree of four factors such as the force, the spring back, the thermal expansion of mold and the solid fraction of material on the dimension accuracy of semi-solid micro-extrusion were analyzed, then the size of weight was determined. The result has a practical significance in controlling semi-solid extrusion size precision.
