| This talk will report on the phase formation and the microstructure development in (often multicomponent) metallic liquids that tend to form glasses upon solidification at sufficiently high cooling rate. Upon slower cooling typically very fine-scale eutectic-like structures can be achieved. The resulting structure depends on both the actual alloy composition and the employed quenching conditions. The existence of quenched-in short- and medium-range order structures for triggering the phase formation will be assessed, and the role of decomposition and heterogeneous nucleation for establishing nanoscale microstructures will be explored. Examples how tuned-in microstructures can be achieved for optimizing the mechanical properties of such alloys will also be given. |
