Abstract Electric resistivity measurements and X-ray diffraction analysis wereperformed to study the isothermal phase transformation in amorphous Au-Siribbons with eutectic composition prepared using melt-spinning technique. A seriesof phase transformations take place spontaneusly at room temperature and accelerateat elevated temperatures. Four stages of the transformation from amorphous state tothe equilibrium state can be distingushed. Discussion on the structural character ofthe metastable phases indicates that Hume-Rothery electron compounds and size fac-tor compounds could form during isothermal aging.
