Popis: Metallography, X-ray diffraction, thermal analysis, electrical resistance and hardness measurements were employed in the study of the zirconium-tantalum system and the determination of its phase diagram. The diagram is a eutectic type and shows limited solubility in the solid state. The maximum solubility of tantalum in α-zirconium at 790°C is less than 022 at. per cent while β-zirconium will dissolve 16 at. per cent of tantalum at 1585°C. Maximum solubility of zirconium in tantalum is. 17 at. per cent at 1585°C. The eutectic occurs at 1585°C and 34 at. per cent tantalum. A eutectoidal transformation of the solid solution based on fl-zirconium takes place at 790°C; the eutectoidal composition is 7 at. per cent tantalum.
