Abstract

Iron aluminides are one of the most attractive intermetallics for commercial applications due to their excellent corrosion resistance in combination with high specific strength. Proper design of thermomechanical parameters and precise control of the microstructural evolution are essential for successful processing of these alloys. This research evaluates the deformation behavior of P/M iron aluminide and discusses the importance of the processing parameters. Iron aluminide alloy powder was consolidated to full density by hot pressing. Cylindrical compression specimens were machined from the compacts and subjected to hot compression tests in order to characterize the material behavior under various thermomechanical conditions. Moreover, numerical simulations of the investigated alloy forging were performed. The boundary conditions for the simulations were prepared on the base of the experimental tests. Chosen results of the simulations were compared with the results of forging the investigated alloy performed in industrial conditions. The study showed good agreement of the experimental and numerical modeling results, what confirmed a proper design of the boundary conditions used in this study.
