摘要：

The influence of the Mn content on the hot deformation properties of austenitic binary Fe-Mn alloys containing 1 to 20 mass pet Mn has been investigated for the first time. The influence of the Mn content on the constitutive equations was determined for the temperature range of 950 degrees C to 1250 degrees C and the strain rate range of 0.1 to 2 s(-1). The activation energy for hot working increased with increasing Mn content, and dynamic recrystallization was observed for all the Fe-Mn binary alloys. The Mn was found to delay dynamic recrystallization. An increase in the Mn content resulted in an increase of both the peak stress sigma(p) and the corresponding peak strain e, thus revealing the pronounced influence of Mn on the hot deformation process.
