Amorphous metals, or metallic glasses, represent the extreme case of rapid solidification metals technology, since they are formed by quenching from the melt so abruptly that no crystallization can take place. Because of the remarkable scientific and technical properties of the amorphous metals, R&D efforts relating to these materials have been vigorous since their discovery twenty years ago. At the present time, Allied Corporation is bringing its continuous casting pilot plant on-line and the prospects of large volume quantities at sharply reduced prices is intensifying the development of applications of the amorphous metals. A brief overview of amorphous metals technology and of the characteristics of these materials is given, followed by a description of their application to the electric power, electronics, transduction, security and metal-joining industries.
