Fatigue of additive manufactured Ti-6Al-4V, Part II: The relationship between microstructure, material cyclic properties, and component performance

Part I of these two-part paper series focused on the process and structure relationships, effect of powder feedstock, fabrication parameters, and post fabrication treatments on the resulting microstructure, defect characteristics, and surface quality of the fabricated Ti-6Al-4V parts. This second part extends the study by evaluating the effect of the aforementioned factors on axial, torsion, and multiaxial fatigue behavior of the additively...
