Abstract

Abstract: The change of electrical resistivity during the glass-to-quasicrystalline (QC) transformation is studied in the Hf65 Al7.5 Ni10 Cu12.5 Pd5 (HfPd), Zr70 Pd20 Ni10 (ZrPd), Zr69.5 Cu12 Ni11 Al7.5 (ZrAl), Zr65 Al7.5 Cu7.5 Ni10 Ag10 (ZrAg) and Ti40 Zr25 Cu12 Ni3 Be20 (TiZr) alloys, which is further correlated with the GFA. Different from other samples only contain amorphous phase, QC phase directly precipitated from the melts in HfPd ribbon and ZrAg rod, while crystalline phase was further found in the ZrAl rod, indicating that the GFA for five alloys follows the sequence: TiZr > ZrAg > ZrAl > ZrPd > HfPd. Meanwhile, electrical resistivity changes from increment for the HfPd, ZrPd and ZrAl ribbons with worse GFA to a continuous decrement until Tx2 in both ribbon and bulk ZrAg and TiZr MGs with better GFA. This difference is attributed to different types and their fraction of full icosahedra in these alloys. Favorable full icosahedra for better GFA would be more stable and lead to slower transition rate into QC phase as confirmed by TEM analyses. The findings suggest that the change of electrical resistivity during glass-to-quasicrystalline transformation can represent the GFA for different MGs. Highlights: Electrical resistivity variation is studied in MGs with quasicrystalline phase formation. Quasicrystalline phase induces increment of electrical resistivity in MGs with worse GFA. A long and continuous decrement of electrical resistivity is seen in MGs with better GFA. Electrical resistivity change reflects the GFA for different MGs with QC phase formation.
