Arola, Director of the Applied Masters Program, and Rick Schleusener, PhD student, highlight the critical role of process variability in shaping material reliability. A particular focus is placed on post-processing contributions to fatigue life distributions, comparing the effects of Stress Relief (SR) and Hot Isostatic Pressing (HIP).<\/p>\n<p>Through this discussion, the talk emphasizes how post-processing pathways determine failure origins, scatter in fatigue life, and the overall performance envelope of L-PBF Ti6Al4V, with implications for both research and industrial applications.<\/p>\n<p>You can learn more about this topic in<\/p>\n<ul>\n<li>Whitepaper &#8211; <a href=\"https:\/\/cn.quintustechnologies.com\/knowledge-center\/reducing-fatigue-failure-titanium-alloys-hip-aerospace-medical-am\/\" target=\"_blank\" rel=\"noopener\">Reducing fatigue failure in titanium alloys with HIP<\/a><\/li>\n<li>Technical publication &#8211;<a href=\"https:\/\/cn.quintustechnologies.com\/knowledge-center\/microstructure-mechanical-lpdf-ti-6al-4v\/\" target=\"_blank\" rel=\"noopener\">\u00a0Microstructure and mechanical properties of L-PBF Ti-6Al-4V after HIP with varied temperatures &amp; cooling rates<\/a><\/li>\n<\/ul>\n","protected":false},"featured_media":40628,"menu_order":0,"template":"","knowledge-center_materials":[182],"knowledge-center_processes":[147],"knowledge-center_language":[135],"knowledge-center_type":[131],"knowledge-center_industry":[94,162,163,126,189,188],"knowledge-center_topic":[112],"class_list":["post-40626","knowledge-center","type-knowledge-center","status-publish","has-post-thumbnail","hentry","knowledge-center_materials-titanium-alloy","knowledge-center_processes-additive-manufacturing","knowledge-center_language-english","knowledge-center_type-tech-talks","knowledge-center_industry-aerospace","knowledge-center_industry-defence","knowledge-center_industry-energy","knowledge-center_industry-medical","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\/40626","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\/40628"}],"wp:attachment":[{"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/media?parent=40626"}],"wp:term":[{"taxonomy":"knowledge-center_materials","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_materials?post=40626"},{"taxonomy":"knowledge-center_processes","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_processes?post=40626"},{"taxonomy":"knowledge-center_language","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_language?post=40626"},{"taxonomy":"knowledge-center_type","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_type?post=40626"},{"taxonomy":"knowledge-center_industry","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_industry?post=40626"},{"taxonomy":"knowledge-center_topic","embeddable":true,"href":"https:\/\/cn.quintustechnologies.com\/en\/wp-json\/wp\/v2\/knowledge-center_topic?post=40626"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
