Accurate analyses may help optimise the process, manage smoke sensitivity materials, and give precious inputs for EB-PBF process modelling and simulation. The major issue in obtaining such kind of information is related to the working conditions of EB-PBF: high temperature and vacuum environment. Moreover, the powder bed should be considered a porous material. Using ad-hoc designed samples and experiments, this work presents an analysis of the thermal behaviour of the Ti6Al4V sintered powder in the EB-PBF process. An experimental campaign has been carried out to evaluate the variation of thermal conductivity of Ti6Al4V sintered powder with the powder thickness and the temperature up to 800\u00a1C, which corresponds to the common working temperature for processing Ti6A4V by EB-PBF.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Keywords<\/strong>: Electron beam powder bed fusion; Thermal conductivity; Ti6Al4V; Sintering<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Video presentation<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-video\"><video height=\"1080\" style=\"aspect-ratio: 1920 \/ 1080;\" width=\"1920\" controls src=\"https:\/\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Manuela_Galati.mp4\"><\/video><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Presenting author<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-background\" style=\"background-color:#f3f4f5\"><tbody><tr><td><\/td><td><\/td><td><\/td><\/tr><tr><td><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"140\" class=\"wp-image-2966\" style=\"width: 150px;\" src=\"https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/foto-Galati.jpg?resize=150%2C140&#038;ssl=1\" alt=\"\" srcset=\"https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/foto-Galati.jpg?w=598&amp;ssl=1 598w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/foto-Galati.jpg?resize=300%2C279&amp;ssl=1 300w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/foto-Galati.jpg?resize=150%2C140&amp;ssl=1 150w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/td><td><strong>Name:<\/strong><br><br><strong>Affiliation:<\/strong><br><br><strong>Email:<\/strong><\/td><td>Manuela Galati<br><br>Politecnico di Torino, Italy<br><br>manuela.galati@polito.it<\/td><\/tr><tr><td><\/td><td><\/td><td><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>by Galati Manuela, Elena Campagnoli, Valter Giaretto, Luca Iuliano (Italy) Abstract The understanding of thermal behaviour of the sintered powder is a crucial feature in the electron beam powder bed fusion (EB- PBF) process.
