Improved performance of structural materials in extreme environments has been actively searched for many decades. Recently developed concentrated solid solution alloys (CSAs) exhibit significant chemical disorders. In CSAs comprised of 3d transition metals, ferromagnetic Ni, Fe, and Co couple antiferromagnetically with Cr. Having both an increasing number of elements and altered concentrations of specific elements, epically with mixed ferro- and anti-ferromagnetic interactions, energy dissipation rate can be significantly reduced that has a substantial impact on defect dynamics. Recent advances of intrinsic chemical effects on defect dynamics and structural modification in CSAs will be discussed. Understanding how materials properties can be tailored by alloy complexity and their influence on defect dynamics and structural stability may pave the way for new design principles of radiation–tolerant structural alloys.
