چکیده انگلیسی
Ti-based bulk metallic glass (BMG) alloy with the composition of Ti53Cu27Ni12Zr3Al7Si3B1 was prepared by copper molder casting method and ribbon sample was prepared by melt spinning to compare. The thermal instability of this glass phase was examined by using differential scanning calorimetry (DSC) and differential thermal analysis (DTA). The results revealed that the supercooled liquid region (ÎTx), glass transition temperature (Tg) and reduced glass transition temperature (Tg/Tm) of the glassy alloy are detected to be 69, 685 and 0.62Â K, respectively. The crystallization behavior of the Ti-based glass phase was also investigated by annealing the glass phase at series temperatures above Tg. The annealed microstructures were examined by means of X-ray diffraction experiments. The crystallization process of the BMG can be characterized by metastable crystalline phases at the first crystallization step and further transition to stable crystalline phases at high temperature through metastable crystalline phase.
