While AM processes enable unprecedented geometrical design freedom, which can result in significant reductions of component weight, on the other hand they have implications in the fatigue and fracture strength due to residual stresses and microstructural features. This is linked to stress concentration effects and anisotropy that still warrant further research. This Special Issue of Applied Sciences brings together papers investigating the features of AM processes relevant to the mechanical behavior of AM structural components, particularly, but not exclusively, from the viewpoints of fatigue and fracture behavior. Although the focus of the issue is on AM problems related to fatigue and fracture, articles dealing with other manufacturing processes with related problems are also be included.History of engineering and technologybicsscadditive manufacturingAl-Zn-Mg-Cu alloysalloy 718Alloy 718applicationscoatingcontact tip to work piece distancedefectsdeformationdiffractiondirected energy depositiondislocation densityEBMEBSDelectrical stickoutelectron backscattered diffractionelectron beam meltingelectron beam melting (EBM)encapsulationenergy input per unit lengthfatigue crack growth (FCG)Fe-based amorphous coatingfinite element methodGMAWhardnesshot isostatic pressinghydrogen embrittlement (HE)laser claddingmechanical propertiesmetal depositionmicroscopymicrostructural modelingmicrostructuremicrostructure characterisationpost-treatmentpowder degradationprecipitation hardeningpreheatingprocessing strategypropertyrelative densityresidual stressresidual stress/strainRietveld analysisSelective Laser MeltingSLMsurface defectssynchrotronTi-6Al-4VTi55511Ti6Al4Vtitaniumtitanium alloyvacancy concentrationWAAMwire and arc additive manufacturingwire arc additive manufacturingX-ray diffractionXRDHistory of engineering and technologyPederson Robertedt1323410Pederson RobertothBOOK9910557443403321Progress in Metal Additive Manufacturing and Metallurgy3035518UNINA
