Abstract
The deformation of large structural cast A1 components during quenching is difficult to control and easily out of tolerance. Hot sizing based on creep-forming principle is a new technology to correct inaccuracies of parts in shape and dimensions. Thus, creep-ageing curves of Al-Cu-Mn alloy were conducted under constant tensile stresses ranging lOMPa to 150MPa at 175"Co The curves at high stresses were sparse, while at low stresses were dense. Then, a hyperbolic sine type constitutive model was achieved with genetic algorithm. The creep-ageing model was derived mathematically, but in good consistence with experimental curves with average relative error of 3.85%.
