L’article traite des d\u00e9fis pos\u00e9s par la fabrication de pi\u00e8ces en aluminiures de titane (TiAls) en raison de leur faible ductilit\u00e9 et r\u00e9sistance \u00e0 la rupture, malgr\u00e9 leurs applications potentielles dans des environnements \u00e0 haute temp\u00e9rature comme l’a\u00e9rospatiale et l’automobile. Les m\u00e9thodes traditionnelles telles que le moulage et le forgeage ont pr\u00e9valu, mais les proc\u00e9d\u00e9s de fabrication additive (AM) tels que le d\u00e9p\u00f4t direct d’\u00e9nergie (DED), la fabrication additive par faisceau d’\u00e9lectrons (EBAM) et la fusion laser sur lit de poudre (L-PBF) suscitent un int\u00e9r\u00eat croissant pour la production d’aluminiures de titane. <\/p>\n
Des \u00e9tudes r\u00e9centes montrent que ces m\u00e9thodes d’AM sont prometteuses pour le traitement industriel du TiAl. Cet article passe en revue les avantages, les progr\u00e8s, les d\u00e9fis et les solutions potentielles dans l’utilisation des technologies d’AM pour les alliages de TiAl, en mettant l’accent sur les relations processus-structure-propri\u00e9t\u00e9s et en soulignant que la L-PBF est une m\u00e9thode prometteuse pour la fabrication de divers alliages de TiAl. L’article se termine par des suggestions sur les orientations futures de la recherche <\/p>\n","protected":false},"featured_media":32252,"menu_order":0,"template":"","knowledge-center_materials":[529],"knowledge-center_processes":[363],"knowledge-center_language":[135],"knowledge-center_type":[625],"knowledge-center_industry":[347],"knowledge-center_topic":[235],"class_list":["post-38509","knowledge-center","type-knowledge-center","status-publish","has-post-thumbnail","hentry","knowledge-center_materials-intermetallics-fr","knowledge-center_processes-fabrication-additive","knowledge-center_language-english","knowledge-center_type-publication-technique","knowledge-center_industry-aeronautique","knowledge-center_topic-material-densification-fr"],"acf":[],"_links":{"self":[{"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center\/38509","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center"}],"about":[{"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/types\/knowledge-center"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/media\/32252"}],"wp:attachment":[{"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/media?parent=38509"}],"wp:term":[{"taxonomy":"knowledge-center_materials","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_materials?post=38509"},{"taxonomy":"knowledge-center_processes","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_processes?post=38509"},{"taxonomy":"knowledge-center_language","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_language?post=38509"},{"taxonomy":"knowledge-center_type","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_type?post=38509"},{"taxonomy":"knowledge-center_industry","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_industry?post=38509"},{"taxonomy":"knowledge-center_topic","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_topic?post=38509"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
