| Abstract Scope |
Chemical short-range order (SRO) has long been recognized in disordered solid solutions, yet recent work has shown that deliberate engineering of SRO can optimize materials performance. This talk will trace the evolution of first-principles approaches for understanding SRO, beginning with early work establishing the thermodynamic origins of ordering tendencies and the role of coherent phase stability in determining SRO in alloys. Building on these foundations, I will highlight recent examples in which SRO is treated as a design variable rather than simply an observed phenomenon. The first demonstrates how tailored cation ordering in disordered rocksalt cathodes can increase the probability of Li diffusion pathways and enable improved battery materials. The second illustrates how controlling local chemical environments in high-entropy alloys can promote favorable short-range order associated with enhanced corrosion resistance. These examples demonstrate how rational design of SRO can achieve targeted materials properties. |
