Various material variants were produced using different heat treatments, including hot isostatic pressing. Electron microscopy revealed that both pores and \u03b3\/\u03b3\u2032-eutectics initiate cracks, leading to early failure. The findings suggest that remaining \u03b3\/\u03b3\u2032-eutectics may weaken fatigue resistance more than pores. Additionally, proper integrated hot isostatic pressing heat treatments enhance fatigue performance.<\/p>\n","protected":false},"featured_media":32250,"menu_order":0,"template":"","knowledge-center_materials":[176],"knowledge-center_processes":[146],"knowledge-center_language":[135],"knowledge-center_type":[486],"knowledge-center_industry":[94,162,163,189,188],"knowledge-center_topic":[112],"class_list":["post-33013","knowledge-center","type-knowledge-center","status-publish","has-post-thumbnail","hentry","knowledge-center_materials-super-alloy","knowledge-center_processes-casting","knowledge-center_language-english","knowledge-center_type-technical-publication","knowledge-center_industry-aerospace","knowledge-center_industry-defence","knowledge-center_industry-energy","knowledge-center_industry-service-providers","knowledge-center_industry-space","knowledge-center_topic-material-densification"],"acf":[],"_links":{"self":[{"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center\/33013","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=33013"}],"wp:term":[{"taxonomy":"knowledge-center_materials","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_materials?post=33013"},{"taxonomy":"knowledge-center_processes","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_processes?post=33013"},{"taxonomy":"knowledge-center_language","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_language?post=33013"},{"taxonomy":"knowledge-center_type","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_type?post=33013"},{"taxonomy":"knowledge-center_industry","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_industry?post=33013"},{"taxonomy":"knowledge-center_topic","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_topic?post=33013"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
