| 英文摘要 | Voids are always unavoidably introduced into metals fabricated by selective laser melting (SLM), and thus greatly degrade fatigue performance of metals. Such a fatal weakness strongly limits the application of SLM-fabricated metals to load-bearing structural components for the long-term service. Here, the authors found that fatigue strength of SLM-fabricated Inconel 718 is significantly improved after the proper heat treatment route not only due to the elimination of Laves phases and the precipitation of / strengthening phases, but also the appearance of ultrafine-scale acicular phases, which effectively suppressed the degraded effect of voids. The finding may provide a potential strategy to enhance fatigue strength of SLM-fabricated materials by tailoring heat-treatment route. |
