Figure 15 Two selected methods for metallic glass preparation (a) in the melt-spinning process the molten alloys are projected against a spinning wheel (b) in the twin-roller quenching technique the melt is cooled between two rotating wheels. In both processes, the aim is to achieve ultrafast cooling...
