Several columbium base alloys in coated sheet form were evaluated for use as gas turbine engine vane materials. These alloys included FS-85, D-43, Cb-752, and Cb-132. This article describes the mechanical properties of these alloys and the various tests performed during the study. Based on strength, ductility, and weldability, D-43 was found to be satisfactory for use as a turbine vane material. Turbine vanes were subsequently fabricated from D-43, using a welded sheet metal airfoil joined to forged platforms. The product was finish machined to hardware within drawing requirements, coated, and engine tested.
