Paper Title:
Mechanism of Melt Treatment Improving Thermal Stability and Glass Forming Ability of the Al-Ni-Y Amorphous Alloy
  Abstract

The mechanism of melt treatment improving the glass forming ability (GFA) and thermal stability of the Al84.5Ni5.5Y10 (in atomic percentage) alloy was studied. An yttrium-rich metastable high-melting-temperature-phase is found to be responsible for the deterioration of GFA because it induces the heterogeneous nucleation of the crystals in the solidification process. It can be eliminated through melt treatment as adopted in this paper, resulting in stabilizing the thermal stability of the undercooled melt and enhancing the GFA of the investigated alloy with higher thermal stability for the resultant amorphous phase.
