| Abstract: | The research of isothermal multiple-extrusion was put up to a revolving part. By means of numerical simulation the flowing of the material during forming was analyzed, then the engineering tests were carried out based on it. The result indicated that the superduralumin part after isothermal multiple-extrusion was formed with good filling, without deficiency of fold or crack on the surface. In microstrueture the grains were fine and well distributed. The dimension of the part also satis lied its requirements. |
