A New Dental Superalloy System: IV. X-Ray Diffraction Analysis

¹ School of Dentistry, University of Michigan, Ann Arbor, Michigan 48104, USA

X-ray diffraction analysis of the alloy system Co-Ni-Cr-Ta showed that the ternary alloy base consisted of three phases (,, and ). Addition of Ta caused a decrease in the intensity of the lines. Further Ta additions caused diffraction lines characteristic of the intermetallic compound -Co₃Ta. At higher Ta concentrations, the intensity of the lines characteristic of the phase increased and lines characteristic of Co₂Ta appeared.
