Abstract

Two alloys of nominal compositions Zr_41.5Ti _41.5Ni₁₇ and Zr_41.5Hf_41.5Ni ₁₇ have been melt spun at 40 ms^-1 wheel speed. Under this processing condition Zr-Ti-Ni alloy becomes amorphous and the Zr-Hf-Ni alloy precipitates a cubic phase with 4.95 Å lattice parameter in the amorphous matrix. The Zr-Ti-Ni alloy, upon annealing, precipitates a nanoquasicrystalline phase, which at the later stages of crystallisation transforms into cF96 NiZr₂ phase. The amorphous phase in Zr-Hf-Ni alloy upon annealing precipitates the same cubic phase with 4.95 Å lattice parameter. The lower glass forming ability of Zr-Hf-Ni compared to Zr-Ti-Ni and nanoquasicrystallisation in Zr-Ti-Ni alloy can be explained by taking into consideration the atomic size differences among Ti, Zr and Hf.
