| Abstract Scope |
This talk explores the structural diversity that can be achieved in high entropy alloys, multiphase composites and metallic glasses developed through a combination of concepts for designing chemically complex alloys and metallic glasses using rapid quenching and annealing for tuning phase formation and microstructure development. The role of phase transformation upon heating or loading will be critically assessed with respect to structural stability and mechanical behavior. Examples for changes in deformation mechanism, e.g. from crack-controlled to dislocation-dominated deformation or cooperative deformation of shear bands and interfacial sliding, will be discussed and analyzed as ways to control both strength and ductility in a wide range. Besides, also examples for tuning the magnetic properties via composition and process control will be given, attempting to derive guidelines for how to tune the microstructure and properties of non-equiatomic chemically complex alloys with optimized properties. |
