| Abstract Scope |
Oxidation and corrosion of conventional alloys is a complex process. The addition of several principal elements renders forecasting degradation mechanisms in multiprincipal elements nearly impossible. Similarly, when designing for these regimes, taking into account the complex energetic landscapes, local order and resulting interstitial occupancy effects, and finally, multiphase, hierarchical microstructural evolution, it becomes a conundrum. Here we present a coincident approach of “top down” AND “bottom up” enabled by a combination of high fidelity and high throughput modeling and experiments toward an understanding of tunable alloy and passivation evolution toward controlled degradation. We reveal that unlike conventional alloys, this approach must be taken into account when designing alloys, as their surface evolution complexity dictates base alloy behavior. |
