A Fractographic Study of a Circa AD83 Roman Nail

Abstract

Results are presented of a scanning electron microscope fractography study of a circa ADS3 iron nail from the Roman fortress at Inchtuthil, Perthshire, Scotland. The fracture surface studied was created under embrittling conditions of low temperature, an added stress raiser, and high strain-rate loading. Fractography features are discussed in relationship to the classic cataloguing and metallographic examination of the Inchtuthil nails in earlier work by Angus, Brown, and Cleere.
