A nano icosahedral quasicrystalline phase was confirmed as a primary precipitation phase in the melt-spun Zr70Ni10M20(M=Pd, Au and Pt) ternary glassy alloys. It is clarified that the precipitation of the icosahedral phase takes place by diffusion-controlled growth mode with increasing nucleation rate. The formation of the nano scale icosahedral phase also indicates the existence of short-range order correlated with an icosahedral structure in the glassy state.
