Additive manufacturing (AM) of metallic parts is a relatively new procedure. Many industry sectors, such as the aerospace or automotive have started to apply this technology produce some elements, thus reducing costs and weight. Several alloys been employed for AM. Due high strength-to-density ratio, Ti6Al4V alloy probably most used AM in industry. This usually shows good static strength properties. However, presence internal defects surface roughness result fatigue that clearly lower than...
In the present work, fatigue resistance values of Scalmalloy specimens obtained by selective laser melting (SLM) additive manufacturing (AM) are experimentally studied. The levels with and without notches after applying different surface treatments, such as sand blasting, shot peening, isotropic finishing, polishing alone or in combination, analyzed. To understand behavior this material, finishes internal residual stresses Moreover, fracture each sample is observed electron microscopy to...
Shot peening (SP) is frequently used as a palliative measure against metal fatigue in many engineering components. The performance of this surface treatment depends on different factors including the material, shape and loading conditions component, well process parameters. Fatigue improvement due to SP great extent upon in-depth compressive residual stress profile produced specimen. In work, we study optimum for terms behaviour. For task, assume that qualitatively similar by metals. Based...
In the present work a series of fatigue tests on Ti6Al4V SLM parts are analyzed via both SEM and confocal microscopy. On one hand, fracture surfaces studied, common pattern is found, formed by different textures which show complex crack front evolution from initiation in particular internal defect to complete failure. other strength observed highly depend where takes place, so experimental observation that critical entity carried out. Both location within specimen shape considering...
