Atomic-level heterogeneity and defect dynamics in concentrated solid-solution alloys

Performance enhancement of structural materials in extreme radiation environments has been actively investigated for many decades. Traditional alloys, such as steel, brass and aluminum alloys, normally contain one or two principal element(s) with a low concentration of other elements. While these exist in either a mixture of metallic phases (multiple phases) or in a solid solution (single phase), limited or localized chemical disorder is a...
