Differential Scanning Calorimetry

Image picture

The final state of alloys is largely defined by the phase kinetics during casting or heat treatment. By means of differential calorimetry, the team of experienced scientists can determine both the formation and solution temperatures as well as the specific corresponding energies. Apart from the basic phase detection, this analysis is a core element for the optimisation of process windows in the casting process and the heat treatment of aluminium and magnesium alloys.
