A simplified route combined stress relief, HIP, and solution treatment into a single pre-aging step, followed by a single-step aging treatment, cutting total heat treatment time from 42 h to 15 h. The novel HIP1020RQSA process used high pressure (200 MPa), a short soak at 1020 \u00b0C (0.5 h), and rapid quenching (2150 \u00b0C\/min). This approach led to localized recrystallization, pore closure, partial Laves phase dissolution, and no \u03b4 phase. It improved yield strength from 1112 MPa to 1209 MPa while maintaining ASTM F3055\u201314a standards.<\/p>\n","protected":false},"featured_media":32250,"menu_order":0,"template":"","knowledge-center_materials":[176],"knowledge-center_processes":[147,487],"knowledge-center_language":[135],"knowledge-center_type":[486],"knowledge-center_industry":[94,162,163,188],"knowledge-center_topic":[],"class_list":["post-34977","knowledge-center","type-knowledge-center","status-publish","has-post-thumbnail","hentry","knowledge-center_materials-super-alloy","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-energy","knowledge-center_industry-space"],"acf":[],"_links":{"self":[{"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center\/34977","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=34977"}],"wp:term":[{"taxonomy":"knowledge-center_materials","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_materials?post=34977"},{"taxonomy":"knowledge-center_processes","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_processes?post=34977"},{"taxonomy":"knowledge-center_language","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_language?post=34977"},{"taxonomy":"knowledge-center_type","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_type?post=34977"},{"taxonomy":"knowledge-center_industry","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_industry?post=34977"},{"taxonomy":"knowledge-center_topic","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_topic?post=34977"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
