| Abstract Scope |
The control of properties of manufactured products by Selective Laser Melting (SLM) is made difficult since it depends on many complex interactions between the process parameters, the metallurgical state and the mechanical properties. In that context, built materials of Ti-6Al-4V are often subject to inner defects such as porosity that affect both tensile and fatigue properties. In this work, an original approach based on wise choice of set of process parameters (density E, laser power P, scanning velocity V) and 3D X-Ray tomography analysis is proposed. A theoretical approach is proposed to streamline our results and to provide clarifications regarding the link between process parameters of SLM and porosity formation. |
