PHASE EQUILIBRIA IN THE THORIUM-TANTALUM SYSTEM
Journal Article

· J. Less-Common Metals
X-ray, electrical resistance, thermal, and metallographic methods were used to determine the phase diagram of the thorium--tantalum system. The diagram is of the simple eutectic type with a eutectoid reaction associated with the thorium alpha -- beta transformation. The eutectic point occurs at 1565 plus or minus lO deg C and 4.0 plus or minus 0.5 wt% tantalum. No evidence of intermetallic compounds was found and only slight terminal solid solubility was found at either end of the diagram, even at elevated temperatures. The solubility of tantalum in thorium at the eutectic temperature is about 0.4 wt% and below 1340 deg C is less than 0.2 wt%. The solubility of thorium in tantalum was found to be less than 0.2 wt% at the eutectic temperature. (auth)
