Metallographic study of cracks formation factors in Inconel 718 and waspaloy during welding by electron beam and the tungsten inert gas process

Creators

Description

Study of physico-chemical aspects of cracks formation during welding of Inconel 718 and waspaloy. In both alloys cracks are caused by an intergranular or interdendritic decohesion at the level of liquid films under stress produced by the welding thermal cycle. Constraints repartition, liquation and external sollicitations influence are studied

Abstract (French)

Etude des aspects physico-chimiques de la fissuration lors du soudage de l'Inconel 718 et du waspaloy. La fissuration a des causes communes pour les deux alliages: decohesion intergranulaire ou interdendritique au niveau de films liquides sous l'action des tensions developpees par le cycle thermique du soudage. On a etudie la repartition des contraintes la liquation et l'influence des sollicitations externes
