Abstract

Deux grandes classes de procédés ont été employées par les forgerons d’aciers dès le premier millénaire av. J.-C. A partir de deux exemples typiques nous montrons comment l’interprétation des examens métallographiques avec des outils modernes tels que MEB et MEBFEG permet de reconstituer ces techniques. Un échantillon de l’époque mérovingienne illustre la fabrication de lames figurées par multiples opérations de soudage puis forgeage. Un échantillon de wootz prélevé dans une lame du XVIIIe siècle illustre le forgeage du fameux acier fondu de Damas.
