摘要：Substitution of Co and Ni for Fe in an Fe75P10C10B5 metallic glass effectively increases the stability of supercooled liquid and glass-forming ability. The bulk metallic glasses with large supercooled liquid region (Delta T-x) exceeding 50 K and the critical sample diameter (d(c)) of over 1 mm were obtained in a wide composition range from 30 to 60 at.% Fe, 0 to 45 at.% Co and 0 to 40 at.% Ni in the (Fe, Co, Ni)(75)P10C10B5 alloy system by copper mold casting. An Fe40Co20Ni15P10C10B5 alloy shows maximum d(c) of 2.5 mm, largest Delta T-x of 60 K, low glass transition temperature of 675 K, low viscosity on the order of 10(8)-10(9) Pa s in the supercooled liquid state, high compressive yield strength of 2860 MPa with a distinct plastic strain, and good soft magnetic properties, i.e., rather high saturation magnetization of 1.13 T and low coercive force of 3.8 A/m. The nano-scale Fe40Co20Ni15P10C10B5 glassy patterns were precisely formed by imprinting, indicating its good thermoplastic formability. (C) 2016 Published by Elsevier B.V.
