Abstract Scope |
Refractory materials used in high temperature applications can benefit greatly from the novel processing techniques of additive manufacturing. These techniques can be applied to particularly difficult to process materials such as pure Tungsten to produce complex geometries. Obtaining high density and defect free material is not a trivial task due to their high melting points and often requires high processing temperatures. Here we present our work on the processing of pure Tungsten using electron beam powder bed fusion to produce fully dense, crack-free material along with evaluations of the microstructure and mechanical properties for varying processing conditions. |
