PILOT PRODUCTION AND EVALUATION OF TANTALUM ALLOY SHEET.
Abstract
This quarterly report describes the fabrication and melting of the first melt electrodes of T-222. The first melt ingots have been fabricated into second melt electrodes for the production of 4 inch diameter ingots. A phase identification study has confirmed the presence of carbide phases in T-222 after various solution and aging treatments. The dimetal carbide, which is predominately Ta2C, is stable in solution treated T-222 at temperatures up to 2400F while a monocarbide phase which is predominately Hf C(1-x) is stable at higher temperatures. It has also been confirmed that prior deformation favors the precipitation of the hafnium rich monocarbide at temperatures below 2400F. (Author)
