PILOT PRODUCTION AND EVALUATION OF TANTALUM ALLOY SHEET.
Abstract
The evaluation of T-222 (Ta-9.6W-2.4HF-0.01C) sheet was continued. A second 3 in. diameter in got of T-222 was melted and processed to sheet to provide additional material for evaluation. Tensile properties of sheet produced from a single AC arc melted ingot were comparable at 2400 F to properties of sheet produced from a double AC melted ingot. At 3000 F the single AC melted material showed abnormal scatter in the data, while double arc melted material showed consistent properties. Several smaller heats of experimental alloys were also melted and processed to sheet. Phase identification studies of T-222 were also continued with emphasis on the development of a reliable technique for 2ulk extraction of precipitated phases from Ta-W-HF-C alloys. (Author)
