【 摘 要 】

A nanoscale icosahedral (I) phase was formed in the melt-spun Ti40Zr20Hf20(LTM)(20) (LTM = Ni, Pd, or Pt) alloys. However, in Pd-bearing alloy it is presumed to be a distorted I-phase or a high-order approximation. I phase, Hf2Pt and beta-(Ti, Zr, Hf, Ni) solid solution phases are formed in the arc-melted Ti40Zr20Hf20Pt20 ingot. (c) 2005 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
