Dynamic precipitation in Aluminium Alloys: mechanisms and applications – DYNAMITAL

Submission summary

The aim of the DYNAMITAL project is to gain an in-depth understanding of the mechanisms governing dynamic precipitation in precipitation hardened aluminium alloys, and to explore the potential for new microstructures and properties. In order to predict the competition between acceleration and dissolution of precipitation induced by dynamic effects, and the kinetics of these transformations, the proposed methodology involves particularly in-situ measurements by X-ray scattering. We will conduct a very broad parametric study by studying the effects of temperature, strain rate, initial metallurgical state, supersaturation of alloys as well as the shape of precipitates in relation with the nature of the solute additions. Dynamic precipitation by cyclic deformation will be explored as a means of obtaining microstructures that break away from the usual ones, and the associated properties will be explored.
