| Abstract: | The numerical relationship between the flow stress and parameters of hot and force (deformation temperature, deformation rate and deformation degree) is studied through hot physical simulation. Meanwhile, the regularities of the influence on the parameters of hot and force to formability is discussed qualitatively, and constitutive equation on GH44 nickel based alloy is regressed with mathematic statistics analysisTherefore, a scientific basis is provided for both numerical simulation of hot deformation and rational choice and control of parameters of hot and force |
