Three HIP-cycles were examined: standard, low temperature\/high pressure (LTHP), and super beta. Moreover, an annealed heat treatment group was incorporated to compare against the HIP groups.<\/p>\n<p>The HIP treatment groups behaved similarly during 4-point bending and uniaxial testing, with the LTHP obtaining a superior fatigue life behavior, followed by the standard and super beta HIP groups. In addition, the efficacy of HIP to reduce pores showed better results in the 4-point bending specimens, leading to few defects as fatigue initiators in contrast to the uniaxial specimens.<\/p>\n","protected":false},"featured_media":32250,"menu_order":0,"template":"","knowledge-center_materials":[182],"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-34976","knowledge-center","type-knowledge-center","status-publish","has-post-thumbnail","hentry","knowledge-center_materials-titanium-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-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\/34976","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=34976"}],"wp:term":[{"taxonomy":"knowledge-center_materials","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_materials?post=34976"},{"taxonomy":"knowledge-center_processes","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_processes?post=34976"},{"taxonomy":"knowledge-center_language","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_language?post=34976"},{"taxonomy":"knowledge-center_type","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_type?post=34976"},{"taxonomy":"knowledge-center_industry","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_industry?post=34976"},{"taxonomy":"knowledge-center_topic","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_topic?post=34976"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
