Abstract Scope |
The volume of available data for aluminum alloys is counterintuitively much smaller than the community expects due to the relatively short research history. Nevertheless, the demand for designing and deploying advanced aluminum alloys for industrial applications has increased dramatically. The challenge is that the anticipated timeframe of alloy development is getting shorter than it used to be because of market competitiveness. This presentation will introduce the use of modern high-performance computing to rapidly populate high-fidelity data toward aluminum alloys design. Examples are constructing first-principles databases of solute segregation energies at the interface between key precipitate and aluminum matrix and solute-vacancy clustering in aluminum. This research was supported by the U.S. Department of Energy, Office of Energy Efficiency, and Renewable Energy Vehicle Technologies Program. |
