Designing for cooperative grain boundary segregation in multicomponent alloys Open
Tailoring the nanoscale distribution of chemical species at grain boundaries is a powerful method to dramatically influence the properties of polycrystalline materials. However, classical approaches to the problem have tacitly assumed that…

Multicomponent alloys designed to sinter Open
Powder sintering is a low-energy, net-shape processing route for many new products in the additive manufacturing space. We advance the viewpoint that for future manufacturing, alloys should be designed from materials science principles to …

Grain Boundary Segregation Predicted by Quantum-Accurate Segregation Spectra but not by Classical Models Open
In alloys, solute segregation at grain boundaries is classically attributed to three driving forces: a high solution enthalpy, a high size mismatch, and a high difference in interfacial energy. These effects are generally cast into a singl…

Lath Martensite Microstructure Modeling: A High-Resolution Crystal Plasticity Simulation Study Open
Lath martensite is a complex hierarchical compound structure that forms during rapid cooling of carbon steels from the austenitic phase. At the smallest, i.e., ‘single crystal’ scale, individual, elongated domains, form the elemental micro…
