Differential scanning calorimetry as a powerful tool for investigation of solid-phase transformations in heating, isothermal annealing and cooling

Solid-solid phase transformations play an important role for the adjustment of machining- and application-properties of metallic materials. During recent years, we developed advanced techniques to analyze solid-solid phase transformation by DSC in a very wide dynamic range. This talk will introduce these techniques, using reactions in aluminium alloys as examples. To achieve the required high dynamic range during cooling we combine three different indirect and direct measuring techniques and five types of DSC devices. Nowadays physically-based models verified with our DSC results moreover allow to predict precipitation volume fractions, solute mass fractions. Latest results on property predictions as function of cooling rate will be presented
