| Abstract Scope |
The utility of binary NiTi, TiMo, and NiMo alloys paves the way for the search for useful NiTiMo ternary alloys. Still, to date, limited experimental work has documented few compositions and calculations of ternary phase diagrams show considerable regions to explore for desirable alloys. This work explores the possibility for useful NiTiMo alloys using directed energy deposition (DED) additive manufacturing to achieve combinatorial synthesis of samples by varying the feed rates of prealloyed NiTi and elemental Mo powders into a laser heat source. Microstructures and chemistries of the DED samples are compared with those created through traditional vacuum arc melting (VAM) of ingots to understand differences between non-equilibrium DED process and near-equilibrium VAM. These results, together with thermal characterization of phase transformations, are presented in this poster. |
