摘要：

A series of Al-Ni-Pt and Al-Pd-Pt alloys containing similar to 50 at.% Al were studied by powder X-ray diffraction, differential thermal analysis and scanning electron microscopy. The formation of a rhombohedral beta'-phase by cooling is interpreted as evidence of the existence of a high-temperature beta-phase of the CsCl-type structure. It is argued that in binary Al-Pt this structure is stable at equiatomic composition and elevated temperatures rather than that of the FeSi-type structure. (C) 2012 Elsevier B.V.
