PILOT PRODUCTION AND EVALUATION OF TANTALUM ALLOY SHEET.
Abstract
Eighteen and twenty-four inch wide T-222 sheet has been obtained by rolling slabs produced by direct forging 4-inch diameter ingots. One sheet has been sampled for detailed chemical analysis and mechanical property studies. Although the investigations are not yet complete, initial recrystallization results show a behavior analogous to that described for T-222 sheet produced for smaller ingots. Size and shape of second phases occurring in solution treated and aged T-222 samples were studied by means of electron microscopy. The dimetal carbide occurring upon aging at 2000 F principally grows as a platelet several thousand angstroms in thickness. The monocarbide developed upon aging at 2800 F appears as a very fine dispersoid submicron in size. (Author)
