| Abstract Scope |
The widespread use of titanium alloys is limited by their high cost, largely resulting from the metal removal process during subtractive manufacturing. Additive manufacturing (AM) provides a potential cost-effective net-shape manufacturing process by maximally avoiding the metal removal cost factor. However, current commercial titanium alloys are not designed for AM processes. The present work is focused on applying the Calculation of Phase Diagrams (CALPHAD) method to the design of a new Ti-Al-Fe based alloy for an AM process. The single laser scanning (SLS) experiment is conducted, coupled with CALPHAD predictions, to investigate the potential performance of a new alloy in a selective laser melting (SLM) process, including scanning topography, analysis of the as-scanned microstructure and comparison with computational results. |
