“…Bulk metallic glasses (BMGs) exhibit remarkable mechanical properties and superb corrosion resistance due to their microstructure of short-range order and long-range disordered atomic arrangement [1][2][3][4][5]. As a result, BMGs have tremendous potential as structural materials in aerospace, electronic devices, medical equipment, and other fields [6][7][8]. Among the various types of existing BMGs, Ti-based BMGs have been paid widespread attention owing to their high specific strength, good corrosion resistance, light weight, biocompatibility, and low cost [9][10][11][12].…”

A series of Ti41Zr25Be34-xNix (x = 4, 6, 8, 10 at.%) and Ti41Zr25Be34-xCux (x = 4, 6, 8 at.%) bulk metallic glasses were investigated to examine the influence of Ni and Cu content on the viscosity, thermoplastic formability, and nanoindentation of Ti-based bulk metallic glasses. The results demonstrate that Ti41Zr25Be30Ni4 and Ti41Zr25Be26Cu8 amorphous alloys have superior thermoplastic formability among the Ti41Zr25Be34-xNix and Ti41Zr25Be34-xCux amorphous alloys due to their low viscosity in the supercooled liquid region and wider supercooled liquid region. The hardness and modulus exhibit obvious variations with increasing Ni and Cu content in Ti-based bulk metallic glasses, which can be attributed to alterations in atomic density. Optimal amounts of Ni and Cu in Ti-based bulk metallic glasses enhance thermoplastic formability and mechanical properties. The influence of Ni and Cu content on the hardness of Ti-based bulk metallic glasses is discussed from the perspective of the mean atomic distance.
