Abstract : In this investigation, flow behavior of Hastelloy C-22 was studied by conducting compression tests at various temperatures and strain rates. Constitutive relations were determined from the flow behavior, and a dynamic material modeling for this alloy was performed. Thus, the optimum processing condition in terms of temperature and strain rate was determined. Microstructural changes during high temperature deformation were also characterized to aid process design engineers to select processing conditions in terms of resulting microstructure.
