Abstract
This study investigates the mechanical and wear properties of Al92.5Fe2.5Cr2.5Ti2.5 alloys prepared via Magnetic Pulsed Compaction (MPC) starting from elemental powders. The potential of MPC-processed Al92.5Fe2.5Cr2.5Ti2.5 alloy for structural applications at both ambient and elevated temperatures has also been studied. The difficulty with which to form supersaturated Al-based solid solutions depends on alloying elements with Fe being the easiest element and Cr the most difficult one to form supersaturated Al-based solid solutions. After exposure to high temperature (up to 500°C), the MPC-processed Al92.5Fe2.5Cr2.5Ti2.5 alloy exhibits an incremental hardness and reaches the maximum at 400°C with minimum wear loss, due to strengthening of intermetallic precipitation.
