Formation of amorphous and icosahedral phases in Ti-Zr-Hf-LTM (LTMÂ =Â Ni, Pd or Pt) alloys

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 β-(Ti, Zr, Hf, Ni) solid solution phases are formed in the arc-melted Ti40Zr20Hf20Pt20 ingot.
