Abstract

A new amorphous alloy system of Ti-Cu-Ni-B-Sn-Si with high thermal stability of supercooled liquid was found. The temperature interval of the supercooled liquid region before crystallization was above 70 K. The glass transition temperature (T_g) and the reduced glass transition temperature (T_g/T_m) of the liquid as well as the high T_g/T_m leads to the production of bulk amorphous alloy with a diameter up to 1 mm by copper mold casting. The Vickers hardness, Young's modulus and tensile fracture strength of the 1 mm diameter bulk amorphous alloy are 620, 110 GPa and 2100 MPa, respectively. The fracture surface exhibits a vein-like morphology, typical for many ductile amorphous alloys.
