Tests and Examinations of theOldHône-BardRailwayBridge

Abstract

Mechanical and metallographic tests were run on surviving fragments of the late-19th-century Hone-Bard railway bridge demolished in the Sixties to assess the characteristics of the “agglomerated” (similar to «wrought») iron used in their construction. An explanation is also offered of the surprising discrepancy between the lab data for this iron and its brilliant service record.
