A water quenching method is used to produce as-cast Zr48Cu 36Al8Ag8 rods with diameters from 20 mm to 25 mm. The microstructures of the as-cast samples were investigated by X-ray diffraction, optical microscopy and scanning electron microscopy. Furthermore, the crystallization behavior of the Zr48Cu36Al 8Ag8 glassy alloy was examined by XRD and transmission electron microscopy. Based on the results obtained one can assume that the simultaneous precipitation of the Zr2Cu+AlCu2Zr eutectic phases is the possible reason for the high stabilization of the quaternary Zr48Cu36Al8Ag8 supercooled liquid.
