Las velocidades de enfriamiento m\u00e1s r\u00e1pidas (100 \u00b0C\/min, 2000 \u00b0C\/min) a 920 \u00b0C promovieron una estructura \u03b1 bilaminar, y 2000 \u00b0C\/min mejoraron la resistencia. Las temperaturas HIP m\u00e1s bajas (800 \u00b0C, 200 MPa) minimizaron el engrosamiento, mejorando la resistencia, mientras que el enfriamiento lento (12 \u00b0C\/min) condujo a la mayor resistencia al limitar la formaci\u00f3n de martensita ortorr\u00f3mbica. A 1050 \u00b0C, el HIP redujo la textura cristalogr\u00e1fica y dio lugar a granos \u03b2 anteriores equiaxados, mejorando la isotrop\u00eda, pero la velocidad de enfriamiento de 2000 \u00b0C\/min no impidi\u00f3 la formaci\u00f3n del l\u00edmite de grano \u03b1, que disminuy\u00f3 la resistencia y el alargamiento. Se utiliz\u00f3 el An\u00e1lisis de Componentes Principales (ACP) para analizar el conjunto de datos.    <\/p>\n","protected":false},"featured_media":32256,"menu_order":0,"template":"","knowledge-center_materials":[551],"knowledge-center_processes":[274,575],"knowledge-center_language":[135],"knowledge-center_type":[626],"knowledge-center_industry":[262,258,263,269],"knowledge-center_topic":[259],"class_list":["post-37944","knowledge-center","type-knowledge-center","status-publish","has-post-thumbnail","hentry","knowledge-center_materials-titanium-alloy-es","knowledge-center_processes-fabricacion-aditiva","knowledge-center_processes-hip-y-tratamiento-termico","knowledge-center_language-english","knowledge-center_type-publicacion-tecnica","knowledge-center_industry-defensa","knowledge-center_industry-industria-aeroespacial","knowledge-center_industry-industria-espacial","knowledge-center_industry-industria-medica","knowledge-center_topic-densificacion-de-materiales"],"acf":[],"_links":{"self":[{"href":"https:\/\/quintustechnologies.com\/es\/wp-json\/wp\/v2\/knowledge-center\/37944","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/quintustechnologies.com\/es\/wp-json\/wp\/v2\/knowledge-center"}],"about":[{"href":"https:\/\/quintustechnologies.com\/es\/wp-json\/wp\/v2\/types\/knowledge-center"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/quintustechnologies.com\/es\/wp-json\/wp\/v2\/media\/32256"}],"wp:attachment":[{"href":"https:\/\/quintustechnologies.com\/es\/wp-json\/wp\/v2\/media?parent=37944"}],"wp:term":[{"taxonomy":"knowledge-center_materials","embeddable":true,"href":"https:\/\/quintustechnologies.com\/es\/wp-json\/wp\/v2\/knowledge-center_materials?post=37944"},{"taxonomy":"knowledge-center_processes","embeddable":true,"href":"https:\/\/quintustechnologies.com\/es\/wp-json\/wp\/v2\/knowledge-center_processes?post=37944"},{"taxonomy":"knowledge-center_language","embeddable":true,"href":"https:\/\/quintustechnologies.com\/es\/wp-json\/wp\/v2\/knowledge-center_language?post=37944"},{"taxonomy":"knowledge-center_type","embeddable":true,"href":"https:\/\/quintustechnologies.com\/es\/wp-json\/wp\/v2\/knowledge-center_type?post=37944"},{"taxonomy":"knowledge-center_industry","embeddable":true,"href":"https:\/\/quintustechnologies.com\/es\/wp-json\/wp\/v2\/knowledge-center_industry?post=37944"},{"taxonomy":"knowledge-center_topic","embeddable":true,"href":"https:\/\/quintustechnologies.com\/es\/wp-json\/wp\/v2\/knowledge-center_topic?post=37944"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
