Transportation industries are in search for high-strength, lightweight materials. The AlFeSi ternary system is a lightweight and low-cost alloy that has shown excellent mechanical properties and high-temperature resistance. The aim of this research is to develop AlFeSi-based alloy powders for additive manufacturing processes. The intermetallic Al4Fe1.7Si is of particular interest due to its low theoretical density and potential mechanical properties. In the present study, AlFeSi alloys were fabricated via arc melting. Each alloy was annealed at 600, 700 and 800°C. The phases present in the alloys where characterized by Energy-dispersive X-ray spectroscopy and X-ray diffraction. Preliminary results showed that the AlFeSi alloys fabricated contain more than 50% volume of the desired phase. Values from 600 to 800 HV were obtained for these ternary alloys.
