The glass-to-icosahedral phase transformation in Zr{sub 70}Pd{sub 20}Ni{sub 10} and Zr{sub 65}Al{sub 7.5}Cu{sub 7.5}Ni{sub 10}Ag{sub 10} glasses was examined by the electrical resistivity measurement performed with a heating rate of 0.67 K/s. The resistivity increased with the promotion of icosahedral precipitation in Zr{sub 70}Pd{sub 20}Ni{sub 10} glass. On the other hand, Zr{sub 65}Al{sub 7.5}Cu{sub 7.5}Ni{sub 10}Ag{sub 10} glass exhibited the decrement of the resistivity according to the evolution of icosahedral phase. The latter was qualitatively explained by the drop of the resistivity of supercooled liquid phase due to the transfer of oxide atoms into the icosahedral phase. Also, the low temperature resistivity experiment showed that the conductivity of glassy and icosahedral phases might obey the weak localization model of conduction electrons. {copyright} 2001 American Institute of Physics.
