| Abstract: | Extrusion is the main method of metal superplasticity forming, therefore, a extru- sion experimental method was proposed to evaluate the metal superplasticity and a corre- sponding experiment device was designed. Taking the brass as experiment material, the flowablity of samples was measured in different extrusion temperature and pressure and the flow state and rule during the superplastic forming was analyzed. The optimal process parameters of superplasticity forming was obtained and the practical value of evaluating the metal superplasticity by the extrusion experimental method was verified. |
