| Abstract Scope |
Among the various additive manufacturing (AM) techniques, laser powder bed fusion for metals (PBF-LB/M) has emerged in recent years as a reliable method for processing aluminum alloys with transition metals (TMs) and rare earth elements (REEs) as primary alloying elements. Al-TM-REE alloys produced via PBF-LB/M are particularly appealing as high-strength materials for elevated-temperature applications, offering a lightweight and cost-effective alternative to heavier materials like steels or titanium alloys when operating temperatures remain below 573 K. However, research on aluminum alloys with high TM and REE content remains limited. This study investigates the mechanical properties of an Al-8Fe-4Ce alloy fabricated by PBF-LB/M through microhardness and nanoindentation. The samples were subjected to prolonged thermal treatments at temperatures up to 673 K. Moreover tensile tests were performed at 523 K. |
