Abstract
The formation of nanoquasicrystalline phase is reported directly from the liquid on melt spinning over a wide range of wheel velocities of 10-30 m/s in Zr-Pd system at the eutectic composition (Zr75Pd25 alloy). The earlier studies in the Zr-Pd system (Zr70Pd30 and Zr65Pd35 alloys) showed nanoquasicrystallization on annealing of the amorphous phase obtained by melt spinning. Based on the existing results in various systems, a large negative enthalpy of mixing and/or existence of Frank-Kasper-type phases appear to be the crucial criteria for the formation of nanoquasicrystalline phase in any system.
