Gd-Ni-Al bulk glasses with great glass-forming ability and better mechanical properties

A series of Gd-Ni-Al ternary glassy alloys with the maximum diameter of 4 mm were obtained by common copper mold casting. The maximum values of the reduce glass transformation temperature (T _g/T _m) and the distance of supercooling region ΔT _x of these alloys in this study were 0.648 and 50 K, respectively. The compressive fracture strength (σ _f) and Young's modulus (E) of Gd-Ni-Al glassy alloys were 1,240-1,330 MPa and 63-67 GPa, respectively. The magnetic properties of these BMGs were investigated. The Gd-Ni-Al bulk glassy alloys with great glass forming ability and good mechanical properties are promising for the future development as a new type of function materials.
