Experimental and thermodynamic assessment of the Nd–Ti system

The phase equilibria of the binary Nd–Ti system have been directly assessed at elevated temperatures between T=1000 and 2100 K by combining conical nozzle levitation with in situ high-energy synchrotron X-ray diffraction. Nd–Ti is a monotectic system. The coexistence of two liquids above the monotectic temperature T=1840±20 K was directly observed by the occurrence of two diffuse diffraction maxima and experimental data of the binodal curve were extracted. Based on the experimental data a self-consistent thermodynamic description of the Nd–Ti system is derived.
