The development of advanced structural alloys with performance meeting the requirements of extreme environments in nuclear reactors has been long pursued. Recent success in synthesizing concentrated solid-solution alloys (CSAs) has vastly expanded the compositional space for new alloy discovery. Their wide variety of elemental diversity sets CSAs apart from traditional dilute alloys. To take advantage of property enhancement by tuning chemical disorder, research has been conducted on synergistic effects involving valence electrons and atomic-level and nanoscale inhomogeneity in CSAs composed of multiple transition metals. Knowledge of tunable chemical disorder in CSAs may advance the understanding of the substantial modifications in element-specific alloy properties that effectively mitigate radiation damage and control a material’s response in extreme environments.
