概述了最近的研究工作，以获得通过粉末增材制造（AM）工艺，包括直接能量沉积（DED）和粉末床熔合（PBF）方法，利用激光或电子束作为能源的金属零件的疲劳行为和失效机制的理解。固有的一些挑战，表征AM金属在循环载荷下的力学行为进行了讨论，重点是残余应力对疲劳抗力的影响。此外，一个方面有关的AM部件的结构完整性有关的疲劳行为在非常高的周期，并与那些传统制造的同行进行比较。
An overview on recent research efforts is presented to obtain an understanding on the fatigue behaviour and failure mechanisms of metallic parts fabricated via powder-based additive manufacturing (AM) processes, including direct energy deposition (DED) and powder bed fusion (PBF) methods, utilizing either laser or electron beam as an energy source. Some challenges inherent to characterizing the mechanical behaviour of AM metals under cyclic loading are discussed, with emphasis on the effects of residual stresses on their fatigue resistance. In addition, an aspect pertaining to the structural integrity of AM parts relating to their fatigue behaviour at very high cycles is presented and compared with those of the conventionally-manufactured counterparts.
