Abstract Scope |
The processing of pure refractory metals through additive manufacturing modalities is often difficult due to the materials sensitivities to high ductile-to-brittle transition temperatures and the high energy densities necessary to densify the materials. To be discussed is the processing science approaches that yield high quality (crack free and >99% dense) pure tungsten. Further, microstructure and mechanical characterization of the material will be discussed, with the impact of the as-built textures on the tensile performance of the material at elevated temperatures. |
