CONSTITUTION DIAGRAM OF TITANIUM-SCANDIUM ALLOYS (in Russian)
The constitution diagram of Ti- Sc alloy, developed with 99.7% pure iodide Ti and 96% pure Sc, shows an unlimited mutual solubility in the liquid state. Eutectic crystallization takes place at 1440 deg C. Additions of Sc to Ti lower the melting point and slightly increase (up to 900 deg ) the temperature of polymorphous titanium transformation. Similar to other rare earth metals, Sc acts as an alpha stabilizer in titanium. The solubility of Sc in alpha titanium at 700 deg C is approximately 2 wt%. Additions of Ti to Sc reduce the temperature of polymorphous transformation from 1450 to 1330 deg C. The Ti- Sc constitution diagram indicates that the components do not form continuous solid solution series. The difference in Ti- Sc electronegativity is approximately 35, which is not favorable to continuous solid solution formation. (R.V.J.)
