BS>The system W- Hf was determined by use of metallographic and x-ray methods. The only intermetallic phase W/sub 2/Hf melts peritectically at 2650 plus or minus 50 deg C. A eutectic between W/sub 2/Hf and beta -Hf solid solution exists at 78 at.% Hf and l930 plus or minus 10 deg C. The addition of tungsten lowers the hafnium transformation; there is a eutectoid at 93 at.% Hf and 1560 deg C. The solubility limits of the terminal solid solutions were determined. (auth)
