Research: Lightweight Materials: Dislocation-Solute Interactions in Al Alloys

Summary

The goal of this project is to develop and apply computer simulation techniques to predict the influence of alloy composition on dislocation motion in aluminum-magnesium alloys. There are three current projects

 

1. Quantum mechanical simulations of dislocation core structures
(Lou Hector, Bill Curtin)

 

2. Molecular dynamic and kinetic MonteCarlo simulations of the interaction of dislocations with solute atoms and precipitates
(David Olmsted, Lou Hector, Yu Qi, Bill Curtin)

 

3. Discrete dislocation simulations of dynamic strain ageing in aluminum-magnesium alloys
(Mike Dewald, Bill Curtin)
