2. Residual stresses and distortions in austenitic stainless steel 316L specimens manufactured by Selective Laser Melting
University essay from Högskolan Väst/Avdelningen för svetsteknologi (SV)Abstract : Residual stresses are one of the major challenges in additive manufacturing of metallic materials today. They are induced during manufacturing because of the rapid local heating and cooling and may cause distortions, cracking and delamination between layers. READ MORE

3. Investigation of material removal techniques for residual stress profile determination on induction hardened steel
University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Abstract : The residual stress profile is a major factor on the fatigue life of components that are subjected to cyclic loading. In order to measure these stresses x-ray diffraction (XRD) is commonly used. The penetration depth of x-rays is limited for this method and thus, it must be combined with material removal to determine in-depth stress profiles. READ MORE
