Abstract
The deformation resistance of Fe–Mn–V–N alloy under different deformation conditions was investigated by hot compression method on thermal simulator. Effects of deformation degree, deformation temperature, and strain rate on deformation resistance were analyzed. The results show that when other conditions are constant, the deformation resistance increases with the increase in deformation degree and strain rate and decreases with the increase in deformation temperature. At the same time, the mathematical model of deformation resistance for Fe–Mn–V–N alloy was established by 1stOpt software using the Levenberg–Marquardt optimization algorithm carried out on the fitting of regression coefficients, which has higher fitting precision.
