  Primary Precipitation Phases in Amorphous Hf65Al7.5Ni10Cu17.5 and Hf65Al7.5Ni10Cu12.5M5 (M = Pd and Pt) Alloys

  摘要：

  Amorphous Hf65Al7.5Ni10Cu17.5, Hf65Al7.5Ni10Cu12.5Pd5 and Hf65Al7.5Ni10Cu12.5Pt5 alloys were prepared and their crystallization process was studied with special emphasis on the primary precipitation phases. For the Hf65Al7.5Ni10Cu17.5 and Hf65Al7.5Ni10Cu12.5Pt5 alloys, the primary precipitation phase is a face-centered cubic Hf2Ni (fcc-Hf2Ni) phase. For the Hf65Al7.5Ni10Cu12.5Pd5 alloy, the primary precipitates contain an icosahedral quasicrystalline phase (I-phase) and an fcc-Hf2Ni phase. Further annealing at higher temperature leads to the decomposition of these primary precipitation phases to other stal;lt: crystalline phases, implying that they are in a metastable state. The effect of Pd addition on the precipitation of an I-phase in the amorphous Hf65Al7.5Ni10CU17.5 alloy was discussed based on the evaluation of chemical affinity and atomic radius.
