Abstract
Recent cleaning and restoration operations carried out on the iron armours belonging to the Oploteca of the “Museo Nazionale” of Ravenna permitted analytical and microstructural studies of the artefacts with the purpose of gathering information about the ironworking technology used for armour manufacture in the 16th-17th century. Small fragments of the plates coming from the different pieces of armour were characterized by optical and electron scanning microscopy and by microhardness tests. Energy dispersive X-ray microanalyses (EDX) were also carried out on copper and gold alloys of some decorations. The studies confirmed the armours’ good knowledge of the hardening processes of steels such as carburising, quenching to martensite, tempering and heat treatments in order to give the material the desired properties.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
