| Abstract | The amorphous ribbons of Cu50Zr40Ni5Al5 alloy were manufactured by rapid solidifica‐ tion. The ribbons were investigated by X‐ray diffraction (XRD), scanning electron microscopy coupled with energy dispersive spectroscopy (SEM‐EDX) and differential scanning calorimetry (DSC). The activation energy of the crystallisation in amorphous alloys was determined by Kissenger technique. The mechanical properties of the ribbons were characterized using Vickers microhardness (HV) tester. According to the XRD and SEM results, the Cu50Zr40Ni5Al5 alloys have a fully amorphous structure. The EDX analysis of the ribbons showed that compositional homogeneity of the Cu50Zr40Ni5Al5 alloy was fairly high. From the DSC curves of the amorphous ribbons, it was deter‐ mined that glass transition temperature (Tg) is around 440–442°C and super‐cooled liquid region (ΔTx = Tx Tx) before crystallisation is around 61–64°C. The microhard‐ ness of the as‐quenched ribbons was measured about 550 HV. However, this micro‐ hardness value decreased with increasing annealing temperature and it was calculated about 465 HV after annealing temperature of 800°C. |
