Abstract

We investigated changes in the electron transport property of stable Pd76Cu6Si18 and Pd40Ni10Cu30P20 metallic glasses, prepared by a melt-spinning technique, following the glass transition. These metallic glasses had a supercooled liquid state after annealing with a heating rate of 0.67 K/s. The slope of resistance as a function of temperature changed after the glass transition for both metallic glasses. However, transmission electron microscope (TEM) observations and X-ray diffraction did not detect crystalline phases or amorphous phase separation in the supercooled liquid region. We discuss briefly the change in the electrical resistivity after the glass transition based on the estimation of the thermal expansion coefficient in the supercooled liquid.
