Both regions exhibited similar hardness and carbide content, but the contour region had a higher density of fine carbides. Post-treatments, such as hot isostatic pressing (HIP) and HIP plus heat treatment (HIP\u2009+\u2009HT), significantly reduced defect content in both regions. Grain coarsening occurred in the contour region after HIP\u2009+\u2009HT. Various factors contributing to grain growth were discussed, and carbide sizes became more similar after post-treatment. Additionally, both regions showed increased hardness after HIP\u2009+\u2009HT compared to the as-built material.<\/p>\n","protected":false},"featured_media":32250,"menu_order":0,"template":"","knowledge-center_materials":[176],"knowledge-center_processes":[147],"knowledge-center_language":[135],"knowledge-center_type":[486],"knowledge-center_industry":[94,162,163,188],"knowledge-center_topic":[112],"class_list":["post-33057","knowledge-center","type-knowledge-center","status-publish","has-post-thumbnail","hentry","knowledge-center_materials-super-alloy","knowledge-center_processes-additive-manufacturing","knowledge-center_language-english","knowledge-center_type-technical-publication","knowledge-center_industry-aerospace","knowledge-center_industry-defence","knowledge-center_industry-energy","knowledge-center_industry-space","knowledge-center_topic-material-densification"],"acf":[],"_links":{"self":[{"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center\/33057","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center"}],"about":[{"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/types\/knowledge-center"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/media\/32250"}],"wp:attachment":[{"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/media?parent=33057"}],"wp:term":[{"taxonomy":"knowledge-center_materials","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_materials?post=33057"},{"taxonomy":"knowledge-center_processes","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_processes?post=33057"},{"taxonomy":"knowledge-center_language","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_language?post=33057"},{"taxonomy":"knowledge-center_type","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_type?post=33057"},{"taxonomy":"knowledge-center_industry","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_industry?post=33057"},{"taxonomy":"knowledge-center_topic","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_topic?post=33057"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
