Notes:
The high temperature deformation behavior and flow instabilities of Ni-Fe-Co basesuperalloy, INCONEL alloy 783 during hot working process were investigated with process mapsconsisting of a power dissipation of dynamic materials model (DMM) and various flow instabilitycriteria. In order to establish the processing map of INCONEL alloy 783, hot compression tests werecarried out under different temperature and strain rate conditions, with true strain up to 0.7. On thebasis of the comparison between processing maps and microstructural analysis, the reliability ofvarious flow instability criteria was estimated. Finally the useful instability criterion for predicting theforming defects was suggested through the compression test results and experimental observations ofactual ring rolling process of INCONEL alloy 783
