Additive manufacturing enables components to have multi-materials with varying composition to match current requirements. However, fabrication of multi-material components using processes which involve melting and solidification limits the combinations of materials used due to formation of phases that adversely impact the properties. Hence, use of solid state additive manufacturing processes would be beneficial in widening the material selection window. Additive Friction Stir (AFS) is a solid-state process which is capable of using powder feedstock of various matrix and reinforcement particles. In this presentation, microstructure and mechanical properties of Al-Fe particulate composite with 2 to 10 vol.% Fe fabricated via AFS process will be discussed. The properties and formation of intermetallic phases were studied and compared with properties of similar composites produced via liquid phase and severe plastic deformation processes. The ability to deposit Al-Fe composites with varying particulate volume fractions using the AFS process will also be discussed.
