Abstract

We reported the relationship among the icosahedral short-range order (ISRO), glass formation and quasicrystal formation in the Zr-Nb-Cu-Ni-Al alloys. The alloys with the Nb addition stabilized ISRO, making the alloys form the amorphous, quasicrystal and crystal with decreasing the cooling rate. Not only bulk glass but also bulk quasicrystal were found to form for these alloys. The structural evolution from the amorphous phase, to the quasicrystal and crystals with the variation in the Nb content or the cooling rate is present. These findings were related to the degree of ISRO, which are advantageous for understanding the glass formation phenomenon.
