Abstract
Using a Gleeble 1500 hot simulator, the dynamic recrystallization (DRX) behavior of Mn-Cr type gear steel was investigated. The experimental results show that the Mn-Cr gear steel exhibits a typical DRX behavior at higher deformation temperature, lower strain rate and smaller initial austenite grain size. The DRX takes place under the conditions that Zener-Hollomon parameter (Z) is less than a critical value Zc. The DXR grains are formed by the bulging mechanism. Activation energy and stress exponent were calculated to be 378. 6 kJ · mol−1 and 5.8 respectively by regression analysis.
