Casting effect on softening of metallic glasses

Correlation between mechanical behavior and glass forming ability of Zr–Cu metallic glasses

“…Then, the amorphous ribbons were prepared from the master alloy ingots using a single-roller melt-spinning apparatus in a purified argon atmosphere. Considering that the overheating temperature of an alloy prior to solidification significantly influences the GFA [16] and the cooling rate affects the microhardness [17], the overheating temperature in each operation was carefully controlled to be about 300 K while maintaining the surface velocity of the copper wheel at 3000 rpm (w35 m/s). The thickness of the as-spun ribbon is 40 AE 3 mm.…”
