Glass-Forming Ability and Crystallization Kinetics of Hf-Ti-Cu-Ni-Al Bulk Metallic Glass


Article Preview

Multi-component Hf45.6Cu27.8Ni9.3Ti5Al12.4 bulk metallic glasses (BMGs) were prepared successfully by casted into the water-cooled Cu mold. Characterization of the casted Hf45.6Cu27.8Ni9.3Ti5Al12.4 rods was carried out by X-ray diffraction. The thermal stability and crystallization kinetics were followed by differential scanning calorimetry. The results show that the alloy Hf45.6Cu27.8Ni9.3Ti5Al12.4 had a critical cylindrical rod diameter for glass formation, Dc, of 7 mm and the largest cross-sectional diameter (about 12.4mm) can be obtained in the ideal condition. The critical cooling rate for glass formation is 6.48K/s. The Hf45.6Cu27.8Ni9.3Ti5Al12.4 BMG has larger glass forming ability and higher thermal stability.
