THE DEVELOPMENT OF OPTIMUM MANUFACTURING METHODS FOR COLUMBIUM ALLOY SHEET. ITEM 1: SUB-CONTRACT FOR THE DEVELOPMENT OF SHEET PROCESS FOR X-110 ALLOY

Abstract

Processing of columbium alloy sheet panels is complete except for sheet flattening. Two 8 inch diameter ingots of the X-110 alloy were converted by extrusion and rolling to 28 inch wide sheet at three gages 0.020, 0.040 and 0.063 inch. Initial evaluation of the sheet has indicated satisfactory gage uniformity and flatness. Target tensile properties were obtained in the 0.040 and 0.063 inch sheet, but high temperature strength of the 0.020 inch sheet was some 20% lower than obtained in the thicker gages. (Author)
