Abstract Scope Chemical short-range order (CSRO), a form of nanoscale special atom arrangement, has been found to significantly alter material properties such as dislocation motion and defect dynamics in various multi-component alloys. The stability of CSRO can in turn be affected by defects. Under radiation conditions, the coupling effect between CSRO and radiation damage may strongly affect the long-term radiation performance. In this work, we use Fe-Ni-Cr and Ni-Co-Cr alloys to demonstrate and discuss the co-evolution of defects and CSRO, based on extensive molecular dynamics simulations. We found that the degree of CSRO can achieve steady state regardless of the initial condition, i.e, CSRO is dynamically evolving to stable level in a decreasing or increasing manner upon continuous irradiation. Furthermore, we consider how grain boundary as defect sinks, would affect CSRO stability. These new understandings assist in clarifying the issue of incorporating the effect of CSRO in investigating radiation-driven microstructural evolution.
