Abstract (en)

A vanadium alloy including chromium and titanium constituents is employed as a substrate for a structural member. To improve the oxidation resistance of the member, chromium or aluminum is diffused into a surface of the substrate thereby forming a gradient of the diffused metal through the substrate and defining an enriched surface layer. The resulting member performs well as a first wall and/or blanket in a fusion reactor in the presence of an oxidizing coolant.
