Abstract
Refractory alloys with their brilliant high-temperature tolerance earn a place for applications in extremely harsh environments. Recent development in additive manufacturing technologies speeds up these alloys' design and forming processes before entering the market. However, the desire for better microstructures and superior high-temperature mechanical behaviors has never been fed up. As was wished, in this study, an additively manufactured WTaRe alloy with compressive strength, ultimate compressive strength, and strain of 356 ± 15 MPa, 731 ± 15 MPa, and > 40% at 1600 °C is herein developed. Composition characterization after deformation of the as-deposited WTaRe alloy suggests the super high thermal stability of this alloy. Considering the excellent high-temperature mechanical behaviors, the printable WTaRe refractory alloy may serve as an alternative in a high-temperature environment.
