Abstract:Since the first Bulk metallic glasses (BMGs) were synthesized in 1989, [1] striking progress has been made in the preparation of BMG. A great number of multicomponent metallic glass alloys with strong glass-forming ability (GFA) and high thermal stability have been discovered, including Ti, Zr, Fe, Pd, Mg, Cu, Ni, and other metallic glass alloy systems. [2][3][4] BMGs have attracted much attention due to their unique properties, for example, their superior strength and high hardness, excellent corrosion resist… Show more
“…Most recently, a similar quaternary BMG with the nominal composition of Ti-28Cu-15Ni-7Sn (TC4-BMG; in at.%) was synthesized through mechanical-alloying plus vacuum hot-pressing in our laboratory [8]. It appeared that a 10-mm diameter and 2-mm thickness of this amorphous disc was successfully fabricated.…”

“…Various processing routes like casting [23][24][25], hot pressing [26][27][28], extrusion [29][30][31] and thermal spraying [32][33][34][35] employ high temperatures which may cause damage to the CNT structure. Successful retention of CNTs during high temperature processes like plasma spraying and high velocity oxy-fuel spraying has been reported by our group in several previous works [32,35].…”
