Abstract

The hot deformation behavior of INCO718 alloy was investigated by hot compressive tests with Gleeble 3800 thermal simulator in the temperature range from 950 C to 1150 C and strain rate range from 0.1 s 1 to 10 s 1. In consideration of the temperature, the flow stress curves were corrected by one simple and effective method. The result shows that temperature increase becomes more obvious with the increasing of strain rate and decreasing deformation temperature.
