| Abstract Scope |
While multiple alloying elements, including Al, Fe, Re, and Ru, can produce BCC+B2 microstructures in refractory alloys, Ru appears to be the most promising element from a phase stability standpoint. This study focuses on an 80Zr-20Ru (at.%) binary alloy, a near-eutectic composition. The microstructure consists of lamellar BCC and B2 phases in the as-cast condition and blocky (coarsened) B2 precipitates in a BCC matrix in the annealed condition. The phase stability of this alloy during annealing and proton irradiation at 600oC is examined using transmission electron microscopy. Compression testing was conducted at room temperature and at 600 °C, and the alloy exhibits possibly the highest specific strength among all known binary alloys. These experimental results indicate a promising path for designing high-temperature alloys. |
