Description

Do materials produced by additive manufacturing perform as well as their forged or cast counterparts in terms of resistance to oxidation? The behaviour of IN 718 samples produced by laser fusion and electron beam is compared with that of a forged and treated reference alloy

Abstract (French)

Les materiaux issus de la fabrication additive sont-ils aussi performants que leurs homologues forges ou coules, en termes de resistance a l'oxydation ? Le comportement d'echantillons en IN 718 produits par fusion laser et faisceau d'electrons, est compare a celui d'un alliage de reference forge-traite
