Abstract:The isothermal forming process of gyroscope鄄brackets has been studied by numerical simulation. The
effects of billet shape and forming programme on metal flowing behavior has been analized. Accroding to the simula鄄
tion results the forming programme had beens choosen. After isothermal forming, the product was heat treated at
200益伊63 h. The fracture strength reaches 371 MPa, the yield strength reaches 243 MPa and the elongation reaches
4. 1%.
