激光选区熔化成形Al-Si合金高周疲劳性能的研究进展
Research Progress on High Cycle Fatigue Performance ofSelective Laser Melting Formed Al-Si Alloy
摘 要
激光选区熔化（SLM）成形是近年来发展最快的增材制造技术之一，在航空航天、汽车和医学等领域应用广泛。但铝合金粉末具有流动性差、激光反射率高以及热导率高等特点，导致SLM成形件表面粗糙，易形成缺陷，从而影响其疲劳性能。结合国内外对SLM成形Al-Si合金高周疲劳性能的研究现状，综述了成形方向、成形参数、热处理和表面处理对成形件高周疲劳性能的影响及高周疲劳断裂机理，总结了改善疲劳性能的方法，展望了未来SLM成形Al-Si合金疲劳性能的研究重点。

Abstract
Selective laser melting (SLM) has been one of the fastest growing additive manufacturing technologies in recent years, and is widely used in aerospace, automotive, medical and other fields. However, aluminum alloy powder has the characteristics of poor fluidity, high laser reflectivity and high thermal conductivity, resulting in rough surface of SLM forming parts and easy to form defects, which affects its fatigue properties. Based on the research status of high cycle fatigue performance of SLM Al-Si alloy at home and abroad, the influence of forming direction, forming parameters, heat treatment and surface treatment on high cycle fatigue performance and high cycle fatigue fracture mechanism are introduced, the methods of improving fatigue performance are summarized, and the research focus of SLM Al-Si alloy fatigue performance in future is prospected.
