| 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 forming/machining parts, Mo is an excellent candidate for atmosphere-controlled additive manufacturing. This work explores computationally-informed compositions that are produced via Vacuum arc melting (VAM) and are mechanically tested to screen for ductility. Promising compositions are produced in-house as prealloyed powder with the Amazemet RePowder ultrasonic powder production machine. Depositions made on an RPMI 222XR DED-LB system are evaluated for printability and mechanical properties. |
