“…In order to achieve the required mechanical properties with desirable microstructure, the components always formed by hot deformation processes such as forging. The hot deformation behavior is essential that establish the logical relation between these factors and mathematical response of hot deformed materials [4] . It has been widely accepted that a "processing map" is beneficial for optimizing hot working processes and controlling microstructure in this class of material [5~7] .…”

The deformation behavior of a Udimet720Li superalloy under hot compression tests was characterized in the temperature range of 1060~1160°C and strain rate range of 0.001~20s-1. Processing maps were conducted at a series of strains to calculate the efficiency of hot working and to recognize the instability regions of the flow behavior. A Zener-Hollomon parameter is given to characterize the dependence of peak stress on temperature and strain rate. The efficiency of power dissipation of the Udimet720Li superalloy obtained in a strain range of 0.1~0.7 are essentially similar, which indicates that strain does not have a significant influence and the instability region shown in high strain and high strain rates at all temperatures. The regions for the full recrystallization can be divided by the dissolution beginning temperature of primary γ'which are the optimum hot working parameters.
