Experimental facility and inflow characterization All experiments were conducted in the FloWave Ocean Energy Research Facility at the University of Edinburgh, a circular combined wave–current basin designed for scaled testing of offshore renewable energy devices. The tank has a diameter of 25 m and, for the present campaign, was operated in current-only mode with a working

Alloy design The Nb45Ta25Ti15Hf15 alloy was initially designed to balance room-temperature ductility and high-temperature strength, according to ref. 17. In summary, the original rationale for the chosen composition was to introduce a high concentration of group IV elements to promote ductility, but not too much as to promote the formation of brittle hexagonal close-packed and
