| Abstract Scope |
Molybdenum and its alloys are receiving increasing attention for their high strength and impressive thermal properties. With their main detractor being oxidation and difficulty producing parts, Mo is an excellent candidate for atmosphere-controlled 3D printing. This work explores advancements in using laser directed energy deposition (LDED) additive manufacturing to print pure Mo along with first steps towards Mo alloys specifically developed for 3D processes. Vacuum arc melting (VAM) is used to produce new compositions which are mechanically tested and evaluated for use in 3D systems. Emphasis is placed on the search for inoculants and alloying additions that increase ductility while retaining strength at high temperatures. |
