English abstract:
With the thermo-kinetic software MatCalc, simulations of the evolution of precipitates in the course of thermo-mechanical treatment of 6xxx aluminium alloys (Al-Mg-Si) has been carried out.
Precipitation sequence that occurs during age hardening of Aluminium alloy 6016 has been studied by using differential scanning calorimetry (DSC). A large number of changes in the precipitate microstructure occur in a precipitation sequence from the initially supersaturated solid solution and the stable Mg2Si phase. The sequence is as follows: Supersaturated solid solution → Formation of clusters composed of Al and Mg and / or Si →coherent GP-Zones (Guinier-Preston zones) with high Al content → coherent ß´´ precipitates → semicoherent ß´ precipitates → ß (Mg2Si) incoherent stable precipitates. Precipitation kinetics simulations show good agreement with the experimental results
