摘要

选择性激光熔化(SLM)是目前最有前途的金属增材制造技术之一。SLMed铝硅合金已广泛应用于铁路运输、航空航天和汽车工业。近年来，由于SLMed Al-Si合金在关键承重结构中的应用，其疲劳和断裂性能受到了广泛的关注。本文旨在更好地了解SLMed Al-Si合金，特别是AlSi10Mg合金的疲劳和断裂研究的最新进展，重点介绍了缺陷、异质组织、残余应力和后处理方法的影响。此外，还讨论了疲劳和断裂建模方法。最后，展望了未来的研究机遇和面临的挑战。

Fatigue and Fracture Behavior of AlSi10Mg Manufactured by Selective Laser Melting: A Review

Selective laser melting (SLM) is one of the most promising metal additive manufacturing technologies. SLMed Al-Si alloys have been widely used in the rail transport, aerospace, and automotive industries. Recently, the fatigue and fracture properties of SLMed Al-Si alloys have attracted considerable attention due to their application in critical load-bearing structures. This review aims to better understand the recent progress on the fatigue and fracture investigations of SLMed Al-Si alloys, especially AlSi10Mg, with emphasis on the effect of defects, heterogeneous microstructure, residual stress, and post-treatment methods. In addition, fatigue and fracture modeling methods are discussed. Finally, the challenges and future research opportunities are prospected.
