Different HIP conditions and a combined HIP and heat treatment (HT) were evaluated. Porosity decreased from 4% in the as-built state to 3.05% at 1200\u00b0C and 1% at 1500\u00b0C, with further reduction to 0.01% after HIP at 1800\u00b0C followed by HT. Plastic deformation influenced pore size and shape, with lower temperatures causing micro-cracks, while the combined HIP and HT process eliminated cracks and porosity through dynamic recrystallization. Higher temperatures also promoted Mo diffusion from TZM to NbZr1.<\/p>\n","protected":false},"featured_media":32250,"menu_order":0,"template":"","knowledge-center_materials":[175],"knowledge-center_processes":[147,487],"knowledge-center_language":[135],"knowledge-center_type":[486],"knowledge-center_industry":[94,162,126,188],"knowledge-center_topic":[112],"class_list":["post-34972","knowledge-center","type-knowledge-center","status-publish","has-post-thumbnail","hentry","knowledge-center_materials-refractory-materials","knowledge-center_processes-additive-manufacturing","knowledge-center_processes-hip-heat-treatment","knowledge-center_language-english","knowledge-center_type-technical-publication","knowledge-center_industry-aerospace","knowledge-center_industry-defence","knowledge-center_industry-medical","knowledge-center_industry-space","knowledge-center_topic-material-densification"],"acf":[],"_links":{"self":[{"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center\/34972","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=34972"}],"wp:term":[{"taxonomy":"knowledge-center_materials","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_materials?post=34972"},{"taxonomy":"knowledge-center_processes","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_processes?post=34972"},{"taxonomy":"knowledge-center_language","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_language?post=34972"},{"taxonomy":"knowledge-center_type","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_type?post=34972"},{"taxonomy":"knowledge-center_industry","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_industry?post=34972"},{"taxonomy":"knowledge-center_topic","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_topic?post=34972"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
