Le soudage par friction malaxage est un procédé de soudage relativement récent (début des années 90). Il est aujourd'hui utilisé couramment sur des alliages légers mais ne l'est que depuis peu sur les aciers.
L'objectif de nos travaux est de chercher à caractériser la microstructure métallurgique et l'état de déformation et de contrainte après soudage par friction malaxage sur des échantillons d'aciers à haute limite élastique utilisés dans l'industrie navale. Nous chercherons à comprendre les phénomènes métallurgiques qui interviennent en cours de soudage.
Abstract
The friction stir welding is a welding process relatively recent (early 90s). It is now commonly used on light alloys but is only recently on steels.
The objective of our work is to try to characterize the metallurgical microstructure and state of stress and strain after friction stir welding on samples of high strength steels used in the shipbuilding industry. We seek to understand the metallurgical phenomena that occur during welding.
