Landolt-Börnstein - Group III Condensed Matter General remarks


This chapter provides an introduction to application-oriented amorphous ferromagnetic alloys. An amorphous metallic alloy will be obtained, if a metallic melt is cooled down sufficiently quick so that no crystallization can take place. The critical cooling rate which is necessary to suppress crystallization completely depends on the composition of the melt. Amorphous alloys may be produced in the shape of powders, wires, foils or ribbons, where ribbons are the most promising shape with respect to application. They have the potential of being magnetically soft, and one major field of their application is the field of soft magnetic materials. Another consequence of the amorphous structure are special mechanical properties. Amorphous alloys are hard, do not show significant work hardening, and have high yield strength. The inherently thin gauge of amorphous alloys and the special mechanical properties have some consequences concerning the application as a soft magnetic material which are listed here. It should be remarked that the term "metallic glass" is often used for rapidly quenched amorphous alloys.
