Abstract
High-purity vanadium alloys were developed for structural materials in fusion reactor. Precipitates form when Ti concentration is about 1 wt% in highpurity V-4Cr-xTi alloys. Solid solution strengthening is prominent and increases as Ti concentration rises. 1 wt% Ti addition is presumably proper from the viewpoint of scavenging effect and precipitation strengthening.
