Amorphous metals are formed by the shock freezing of metallic melts. The atoms have no opportunity to form a crystalline lattice and solidify in a disordered manner (amorphous). Since the phase transformation from liquid to solid is suppressed in this process, no crystallization nuclei are formed during solidification. These defects in the lattice structure of conventional metals influence the mechanical and electromagnetic properties and lead, for example, to the material showing an increased tendency to corrosion, being brittle or cracking more quickly.
Since amorphous metals do not have lattice structures, no grain and phase boundaries are formed. The material shows excellent mechanical properties, has above average corrosion resistance, is biocompatible and behaves isotropic. For this reason, metallic glasses, as amorphous metals are also called, are excellently suited for a variety of high-tech applications and are interesting, for example, for wear-resistant drive components, stable suspensions, diaphragms for sensor technology or housings for consumer electronics.
