Differential scanning calorimeters (DSC) are scientific instruments used in thermal analysis to measure the energy absorbed or released by a sample as it is heated or cooled. They are used by researchers, scientists, and engineers across many industries for precise measurement and analysis of thermal effects such as melting, crystallization, and glass transitions. Precipitation processes in age hardenable aluminium alloys are often investigated by differential scanning calorimetry (DSC). The endothermic and exothermic peaks of the DSC signal correspond to the dissolution and formation of phases, respectively. However, parasitic effects can lead to an unintended curvature of the DSC signal. Although a baseline correction .3.
