摘要：

Ti-61.67 Zr-17.15 Ni-14.80 Cu-6.38 (atom fraction, %) metallic glass has applications in brazing. Using the hammer-and-anvil technique, Ti61.67Zr17.15Ni14.80Cu6.38 metallic glass was prepared. The crystallization behavior for this metallic glass was investigated by differential scanning calorimetry (DSC), X-ray diffractometry (XRD) and transmission electron microscopy (TEM). There are three stages in DSC curves of crystallization. The reduced glass temperature T-rg is 0.42. The kinetic parameters of crystallization were calculated by a set of equations of the maximum crystallization rate. The crystalline phase formed in the MSI(Metastable stage I) is Zr2Cu, in the MSII is alpha-Ti and in the MSIII is Ti2Ni. This kind of alloy has lower glass forming ability, and the Ti61.67Zr17.15Ni14.80Cu6.38 metallic glass has lower thermal stability.
