THE DEVELOPMENT OF OPTIMUM MANUFACTURING METHODS FOR COLUMBIUM ALLOY SHEET

This technical documentary report describes the development of a manufacturing process for D-43 nobium alloy sheet (Nb 10W 1Zr-0.1C, formerly called X-110). Six thousand pounds of secondmelt electrodes were melted into eight-inch diameter ingots. The ingots were converted by extrusion and rolling to...

Zusammenfassung:	This technical documentary report describes the development of a manufacturing process for D-43 nobium alloy sheet (Nb 10W 1Zr-0.1C, formerly called X-110). Six thousand pounds of secondmelt electrodes were melted into eight-inch diameter ingots. The ingots were converted by extrusion and rolling to twenty-four inch wide sheets in three gages, 0.012, 0.018, and 0.030 in. The material was dispersion-strengthened by solution treatment at penultimate gage at final gage. Sheets of all three gages had consistently high tensile strength at elevated temperature. The sheet processing is described. (Author) Subcontract to Crucible Steel Co. of America, Midland, Pa., Contract AF33 600 39942.
