Analysis for Key Process Parameters during Isothermal Pressure Torsion of 7A60 Aluminium Alloy Cup AITranslate
Abstract AITranslate
The effects of key parameters on forming performance of 7A60 aluminum alloy cup during isothermal pressure torsion were investigated by technological experiments and finite element simulation. The results show that the effect of height to diameter ratio of the blank on cumulative deformation is mainly in upsetting deformation stage. As lower mould torsion speed increases, the forming load is reduced and the torque increases. When lower mould torsion speed is too large, the damage value of transition fillet area of the torsional disk would be greater than 1, and the edge is easy to fracture. The influence is significant of forming temperature on forming load and torque. The continuity of the alloy cannot be destroyed with a torsional shear deformation of less than one ring during forming process,and its strength is improved corn pared with the alloy obtained by conventional extrusion.
