Additive manufacturing (AM) should be tailored to the needs of the industrial sectors. In order to exploit the major advantages of AM in real life applications, a better understanding of the phenomena taking place during AM process is crucial. During the production of an AM component, high thermal gradients cannot be avoided. The material’s thermal gradients are complex due to the layer by layer nature of the process and is inevitable resulting in a complex residual stress distribution. Having knowledge about the magnitude and distribution of the residual stresses is important and there are many techniques that are used in order to characterize them. The aim of this work is to study the effect of the residual stresses in additively manufactured components by means of neutron diffraction and incremental centre hole drilling methods. The effect of the residual stresses in fatigue was also investigated in as-built and stress relieved conditions.
