Abstract: 
The warm-hot deformation behavior of 20CrMnTi steel was studied with hot compression tests at temperature range of 1123~1273 K and strain rate of 0.1~20 s−1. The activation energy for warm-hot deformation is 426.064 KJ/mol. The influences of zener-Hollomon parameter, strain and grain size imposing on the flow stress were analyzed in the temperature range of warm-hot forging. Creep theory and mathematical theory of statistics were used to obtain mathematical models of flow stress. The research and results provide scientific basis for controlling microstructure of forging process through zener-Hollomon parameter.
