摘要：

The phase equilibria of the binary Ce-Zr system have been investigated between 900 K and 1800 K 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 +/- 5 K at the eutectic composition of 1.5 +/- 1 at% Zr. Based on the experimental data a self-consistent thermodynamic description of Ce-Zr phase diagram is derived. (C) 2014 Elsevier Ltd. All rights reserved.
