摘要：
This brief communication gives an overview of fatigue behaviour and assessment of additively manufactured metals. The high cycle fatigue behaviour of as-built and post-processed additively manufactured superalloy 718, stainless steel (316L and 17-4PH), and Ti-6Al-4 V is compared with their wrought counterparts. Further, different approaches used for assessment of the fatigue behaviour are presented. © 2019 The Authors. Material Design & Processing Communications Published by John Wiley & Sons Ltd
