MULTISCALE ANALYSIS OF PRECIPITATE IN Al-Cu ALLOYS

Project description

Eliminating trial-and-error approaches in the design of precipitation-strengthened Al-Cu alloys

Al-Cu alloys have a wide range of engineering applications due to their low density and high strength provide by a fine dispersion of nm-sized precipitates. The EU-funded MAPAA project presents a novel methodology to determine the precipitate structure and alloy strength resulting from high temperature ageing from first principles calculations. The strategy is based in two main pillars. The first one is the determination of the Al-rich part of the Al-Cu phase diagram by means the construction of effective cluster expansion Hamiltonians in combination with statistical mechanics. The information is used as input for phase field modeling to predict the nucleation and growth of precipitates during ageing while molecular dynamics and dislocation dynamics are used to predict the strengthening provided by the precipitates.
