Abstract
The Ti45.50Zr23.89Ni15.91Cu14.70 (at.%) metallic glass was prepared in an arc furnace and hammer-and-anvil equipment, for which the cooling rate during solidification is about 106 K/s. The crystallization behavior for this metallic glass has been investigated by differential scanning calorimetry (DSC), X-ray diffractometry (XRD) and transmission electron microscopy (TEM). There are two stages in the DSC curves. The reduced glass temperature Trg is 0.63. The kinetic parameters of crystallization have been calculated by a set of equations of the maximum crystallization rate proposed by Gao et al. The crystallization phases of Ti2Ni, Zr2Cu and α-Ti were formed in the MSI stage at the same time. A recrystallization process occurred in the MSII stage.
