Abstract : In this investigation, flow behavior of Nickelvac K-500 alloy was studied by conducting compression tests over a wide range of temperatures and strain rates. Constitutive relations were determined from the flow behavior, and dynamic material modeling was conducted on this alloy. Thus, the optimum processing condition in terms of temperature and strain rate was identified. Microstructural changes during high temperature deformation were also characterized.
