The ternary phase diagram Co–Gd–Ti was experimentally assessed. An isothermal section at T=773K is presented. The phase equilibria for Co-contents <70at% are characterized by the coexistence of the binary terminal phases with low solubility of the respective third element. For higher Co-contents one ternary phase GdCo12−xTix (S.G. I4/mmm) exists with a homogeneity range of 1≤x≤2. The liquid phase...
The phase equilibria of the binary La–Ti and La–Zr system have been investigated between 900K and 2300K by combining conical nozzle levitation technique with in situ high energy synchrotron X-ray diffraction. The coexistence ranges of phases as well as experimental data of the liquidus and binodal line were obtained from the analysis of the diffraction data. The monotectic character of the La–Ti system...
The phase equilibria of the binary Nd–Ti system have been directly assessed at elevated temperatures between T=1000 and 2100K 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±20K was directly observed by the occurrence of two diffuse diffraction maxima...
The phase equilibria of the binary Nd–Zr system have been investigated by combining the gas levitation technique with in situ high energy synchrotron X-ray diffraction at elevated temperatures. The Nd–Zr system is of a eutectic type. From the diffraction data the liquidus line was experimentally determined between 1300 and 1800K. At T=1274±10K the eutectic reaction L↔ bcc-Nd+bcc-Zr is evident. The...
The phase equilibria of the binary Ce–Zr system have been investigated between 900K and 1800K by a combining conical nozzle levitation technique with in situ high energy synchrotron X-ray diffraction. From the diffraction data the phase sequences and the liquidus line were determined experimentally. The Ce–Zr system is an eutectic type. The eutectic reaction L↔bcc-Ce+hcp-Zr occurs at T=1113±5K at...
The phase equilibria of the binary Gd–Ti system were studied by combining electrostatic levitation of the melt with high energy synchrotron in situ X-ray diffraction at elevated temperatures. The coexistence of the phases including the liquid was directly proven in the temperature range between T=1000 and 1920K. The Gd–Ti system is of monotectic type characterized by a miscibility gap in the liquid...
The phase equilibria of the binary Gd–Zr system have been investigated by combining electrostatic levitation of the melt with in situ high energy synchrotron X-ray diffraction. The liquidus line was experimentally assessed between 1500 and 1800K from the diffraction data. At T=1495±10K the eutectic reaction L↔bcc-Gd+bcc-Zr is evident. The eutectic composition x=18±2at% Zr is determined from the in...
