Thermal stability and glass-forming ability of new Ti-based bulk metallic glasses
چکیده انگلیسی

New Ti-based metallic glass (Ti53Cu15Ni18.5Al7Si3M3B0.5 (M = Sc, Hf, Ta, Nb)) alloys were prepared by melt spinning and copper mold casting. The effects of foreign atoms on the thermal stability and the glass-forming ability were investigated by X-ray diffraction (XRD), differential scanning calorimetry (DSC) and differential thermal analysis (DTA). The results show that the values of Trgs are 0.619, 0.609, 0.606, 0.597 K and ΔTxs are 58, 54, 85, 78 K, respectively. The foreign atom’s size factor (∥RF − RTi∣/RTi − 0.12∣) and mixing heat factor (∑xiHiF/∑xiWi) are proposed to predict the glass-forming ability and thermal stability, respectively.
