The influence of quenched-in nuclei of icosahedral short range order, proposed as a possible explanation for quasicrystal formation, has been investigated by producing a melt-spun ribbon from previously mechanically alloyed Zr57Ti8Nb2.5Cu13.9Ni11.1Al7.5 glassy powder. A ribbon prepared from highly pure materials forms a quasicrystalline phase during the first stage of the crystallization process, whereas no quasicrystal formation has been detected in the devitrification of the ribbon produced from the mechanically alloyed powder. This finding indicates that the absence of quenched-in nuclei may not be the only reason for the lack of quasicrystal formation in mechanically alloyed powders.
