A constitution diagram was plotted for tantalum--rhenium alloys, and studies were made of the melting point, hardness microstructure, and x-ray diffraction of alloys prepared with 99.9% pure tantalum foils and 99.8% pure rhenium powder sintered at 1600 deg C in vacuum. The phase analysis was made with alloys annealed at 2000 deg C for 5 hr in a vacuum of 10/sup -3/ mm and at 1000 deg C for 560 hr. followed by tempering in water. The melting temperature of the solid solutions drops from 2996 deg C for pure tantalum to 2400 deg C for alloys containing 43.4 to 49% rhenium. Tantalum diffusion in rhenium is less than 5%.
