Miniature sheet-type tension specimens are currently being used in a variety of radiation damage studies conducted in a number of different reactors. Although these specimens are very small (12.7 mm long, 0.25 mm thick, 1.0 mm gage width), they have proven successful in addressing issues encountered in both thermal reactors and anticipated fusion reactors. This paper reviews the results of a number of recent studies that illustrate the range of applicability of these small specimens. When combined with other types of specimens and other types of measurements made prior to tension testing, miniature tension specimens have been found to serve as very useful tools for application to both fundamental studies and alloy screening studies.
