In the mid-1970’s, a race was underway to develop superplasticity in steels. This talk will describe how that research program led to a series of investigations into historical materials starting with Damascus Steels. Subsequently, a wide range of monolithic and laminated steel weapons (e.g., Indonesian krises, the Japanese sword, adze blades) were examined and several intriguing issues investigated. For example, in an attempt to resolve the controversy surrounding the metallurgical origins of a unique laminated iron plate, found in an air channel in the Great Pyramid of Giza in 1837, a program on carbon dating of ancient steels was initiated. In another case, a mystery surrounding certain knives made in the U.S. in the 1920’s was explored and a solution arrived at using modern research. In this presentation, the archaeometallurgy of swords and knives will be discussed starting with the early development of wood, bone, horn, and stone knives and evolving to the present time where modern Bladesmiths use an astonishing range of sophisticated materials and manufacturing methods.
