INVESTIGATION OF THE PLATINUM-RICH PORTION OF THE PLATINUM-TANTALUM PHASE DIAGRAM

Abstract

The Pt-Ta binary system was investigated at two isotherms; 1000 and 1500 C, and at 11 alloy compositions in the range of 50 to 100 at-% Pt. The alloys were examined by x-ray diffraction and metallography. Three intermetallic compounds, Pt2Ta, Pt3Ta, and Pt4Ta were found to exist in this com osition range. The Pt4Ta intermetallicAPPEARED ONLY AT THE 1500 C isotherm. Pt dissolved Ta substitutionally to 90 at-% at 1500 C and to approximately 80 at-% at 1000 C. (Author)
