Methods based on quenching from the melt, such as piston and anvil, double piston, torsion catapult and roller casting (Luborsky, 1980) permit larger quantities of amorphous materials to be obtained. The last of these, also known as melt spinning, is probably the method most used to obtain amorphous ribbons of thickness 10-60 pm, width up to 17 cm and virtually infinite length. In this method, the molten alloy is propelled through a small hole or a slot onto a massive, cold metallic disc rotating...
