Determination of solid/liquid fraction of three aluminium binary alloys using a new single-pan scanning calorimete

Abstract

There is an increased demand for data with higher precision for the enthalpy changes and the fraction of solid/liquid temperatures of materials. Therefore, continuous efforts are often devoted to design calorimeters that can accurately measure materials’ thermophysical properties. In this study, a new single-pan scanning calorimeter was used to measure the transition temperature and enthalpy change of three aluminium binary alloys. Measured results also were compared with the calculated results using thermodynamic software. The measured high accuracy enthalpy data were used to determine transient temperature. It is concluded that the new instrument is a promising device that can achieve reliable and reproducible materials’ thermophysical data.
