Abstract
The methods of metallography, thermal analysis, electrical resistance, and x-ray phase analysis were used to study the system zirconium-tantalum, and the phase diagram was constructed. The diagram for the zirconium-tantalum system is of the eutectic type with limited solubility. The maximum solubility of tantalum in α-zirconium at 790 °C is less than 22 atomic %, and in ß -zirconium at 1585 °C it is 16 atomic %, The maximum solubility of zirconium in tantalum at 1585 °C is 17 atomic %. The eutectic corresponds to 1585 °C and 34 atomic % tantalum. At 790 °C and 7 atomic % tantalum a eutectoid transition of the solid solution based on ß -zirconium takes place.
