The enthalpy sensitivity of liquid fraction has been proposed as a novel criterion for assessing the semi-solid processability. Via experimental analysis and thermodynamic prediction, the enthalpy sensitivity turns out to be more reasonable than previous criterions. Based on criterion of enthalpy sensitivity, the effects of elements Si and Cu on semi-solid aluminium processability were analysed, indicating the approach to develop new alloys. Furthermore, the influences of heat exchange rate on semi-solid processability were investigated. It is suggested that increasing heat exchange rate would benefit the processability but with a sacrifice of the process time window in practice.
