Le traitement thermique peut jouer un r\u00f4le majeur dans l’am\u00e9lioration des performances des alliages coul\u00e9s. L’innovation dans ce domaine continue \u00e0 relever les d\u00e9fis tant pour l’industrie que pour la communaut\u00e9 des chercheurs. <\/p>\n
Le traitement thermique des alliages d’aluminium moul\u00e9s sous pression est g\u00e9n\u00e9ralement une op\u00e9ration critique en raison de l’\u00e9largissement des porosit\u00e9s gazeuses pr\u00e9sentes dans les pi\u00e8ces moul\u00e9es. Le pressage isostatique \u00e0 chaud (HIP) est utilis\u00e9 depuis de nombreuses ann\u00e9es pour densifier les alliages coul\u00e9s et peut garantir l’int\u00e9grit\u00e9 du mat\u00e9riau avant d’effectuer un traitement thermique ult\u00e9rieur pour renforcer davantage l’alliage. <\/p>\n
L’\u00e9quipement HIP moderne permet de combiner le HIP et le traitement thermique (traitement thermique \u00e0 haute pression, HPHTTM<\/sup>), ce qui repr\u00e9sente une approche int\u00e9ressante dans ce domaine, permettant \u00e0 la fois la densification et le renforcement par pr\u00e9cipitation sous pression, dans le m\u00eame cycle de post-traitement.<\/p>\n","protected":false},"featured_media":26827,"menu_order":0,"template":"","knowledge-center_materials":[547],"knowledge-center_processes":[362],"knowledge-center_language":[135],"knowledge-center_type":[586],"knowledge-center_industry":[347,350,244,352],"knowledge-center_topic":[235],"class_list":["post-37764","knowledge-center","type-knowledge-center","status-publish","has-post-thumbnail","hentry","knowledge-center_materials-aluminium-alloy-fr","knowledge-center_processes-moulage","knowledge-center_language-english","knowledge-center_type-webinaire","knowledge-center_industry-aeronautique","knowledge-center_industry-defense","knowledge-center_industry-space-fr","knowledge-center_industry-vehicules","knowledge-center_topic-material-densification-fr"],"acf":[],"_links":{"self":[{"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center\/37764","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\/26827"}],"wp:attachment":[{"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/media?parent=37764"}],"wp:term":[{"taxonomy":"knowledge-center_materials","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_materials?post=37764"},{"taxonomy":"knowledge-center_processes","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_processes?post=37764"},{"taxonomy":"knowledge-center_language","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_language?post=37764"},{"taxonomy":"knowledge-center_type","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_type?post=37764"},{"taxonomy":"knowledge-center_industry","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_industry?post=37764"},{"taxonomy":"knowledge-center_topic","embeddable":true,"href":"https:\/\/quintustechnologies.com\/fr\/wp-json\/wp\/v2\/knowledge-center_topic?post=37764"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
