This chapter describes the melt-spinning technique and the different techniques that have been used to synthesize Bulk Metallic Glasses (BMG) in different alloy systems. Metallic glasses were first synthesized in an Au–25 at.% Si alloy by Pol Duwez and his colleagues in 1960 by rapidly solidifying their metallic melts. The technique of melt spinning has been the most commonly used method to produce long and continuous rapidly solidified ribbons, wires, and filaments. In fact, it is the development of this technique that was mostly responsible for the accelerated progress of the Rapid Solidification Processing technology since the 1970s. An important difference between the technique of melt spinning and the techniques used to obtain BMGs is that the solidification rates required in the latter case are much lower. Wheels for melt spinning have been made from a variety of materials, including copper, stainless steel, chromium, and molybdenum, although copper is the most popular one.
