A description is given of the development of a manufacturing process for D-43 Nb alloy sheet (Nb--10W-- 1 Zr-0.1C, formerly called X-110). Six thousand pounds of second-melt electrodes were melted into eight-inch diameter ingots. The ingots were converted by extrusion and rolled to twenty-four inch wide sheets in three gages, strengthened by solution treatment at penultimate gage and aging at final gage. Sheets of all three gages had consistently high tensile strength at elevated temperature. The sheet processing is described. Sheet quality was emphasized. The gage control was excellent, the majority of sheets being within one-half of the standard tolerances. The results of the quality control inspection are given. Various mechanical and physical properties of final product sheet are also given. (auth)
