| Abstract Scope |
Chemical short-range order (CSRO) has emerged as a central topic in the study compositionally complex alloys. Recent advances in experimental techniques and computational modeling have revealed that CSRO can alter thermophysical properties, such as thermal expansion, heat capacity, and dimensional stability, while its direct impact on mechanical behavior remains a subject of active debate. In this work, we explore the formation, detection, and implications of CSRO across different alloy systems, with emphasis on medium- and high-entropy alloys. Using a combination of high-precision calorimetry, synchrotron, electron and neutron diffraction and atomistic simulations, we investigate both the thermodynamic nature of CSRO and its manifestation as well as its thermodynamic and kinetic nature. Particular attention is given to disentangling CSRO from long-range order and other microstructural effects, aiming to clarify its real role in mechanical performance and functional behavior. |
