研究了熔融纺丝法制备的稳定的pd76cu6si18和pd40ni10cu30p20金属玻璃在玻璃化转变后电子输运性质的变化。这些金属玻璃退火后呈过冷液态，升温速率为0.67 K/s。两种金属玻璃的玻璃化转变后，电阻斜率随温度的变化而变化。透射电镜（TEM）观察和x射线衍射均未发现过冷液区有结晶相和非晶相分离。根据过冷液体的热膨胀系数的估计，简要讨论了玻璃化转变后电阻率的变化。
We investigated changes in the electron transport property of stable Pd76Cu6Si18and Pd40Ni10Cu30P20metallic 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.
