We report on the glass-forming ability and devitrification behavior of Zr60.Cu30Al10, Zr60Cu 25Al10Fe5 and Zr62.5Cu 22.5Al10Fe5 bulk glass-forming alloys on heating. The effect of Fe addition on the structure of Zr-Al-Cu alloys is also discussed. Crystallization kinetics and structural changes in the glassy alloys were studied using X-ray diffraction, transmission electron microscopy, differential scanning and isothermal calorimetry methods. The results indicate that good glass-formers, such as Zr62.5Cu22.5Al 10Fe5, are located somewhat beyond the equilibrium eutectic point. Possible phase separation in the supercooled liquid on heating and electron beam-induced in situ crystallization are observed and discussed.
