Preparation, processing and selected properties of modern melt-quenched alloys

Abstract

Rapidly quenched amorphous and nanocrystalline alloys in form of thin ribbons are for several decades already among traditional materials used in construction, biomedical, catalytic and mainly electromagnetic applications. These alloys exhibit excellent properties tunable by a wide range of tools – compositional optimization, pre-preparation and post-preparation processing. The contribution focuses on recent technologies of preparation of metallic glasses with enhanced thickness and consisting of different alloy layers. Specific processing aspects to optimize the desired properties are presented. Attention is given also to possibilities of using these materials for power electronics, sensors, actuators and mechanical construction elements.
