Theoretical model that predicts the grain size of alloys inoculated with micro- and nano- particle master alloys and cast under an external field (2014–2016)

Abstract:
The aim is to develop a theoretical model that predicts grain size when components are cast under the influence of external fields (electromagnetic, ultrasonic, pulsed electric current and melt shearing treatments) and with the addition of nano-particle master alloys. Refining microstructures by available master alloys is reaching a limit and this limits further improvement in mechanical properties to meet the challenge of new applications requiring, for example, high temperature properties or light weighting (i.e. use of less material). The outcomes will be a new theoretical model, validated numerical models, new casting technologies and highly refined alloys with greater than 25% improvement in mechanical properties.
