摘要：
X-ray diffraction, differential thermal analysis, and electron microscopy are used to study the crystal structures and formation sequence of intermetallics in the Lu-Pd system in a composition range of Pd-(0-50 at %) Lu. The alloys are synthesized using high-purity lutetium. Within the composition range under study, the system is characterized by terminal Pd-based solid solutions with a lutetium content up to 10 at % Lu (at 1000°C) and a number of intermetallics (Lu3Pd4, Lu2Pd3, LuPd, LuPd3, Lu10Pd21). A nonequilibrium bertholide phase is found to form in the composition range from 30 to 45 at % Lu. The phase diagram is given in the composition range Pd-(0-50 at %) Lu. © 2011 Pleiades Publishing, Ltd.
