Research on the Yield and Fracture Behavior of Microporous AlSi10Mg Generated by Selective Laser Melting in Local Stress Concentrations Caused by Different Notches

Source

During the manufacturing of components by selective laser melting, voids of different sizes can occur due to the complex and transient interaction of the laser beam, powder and process atmosphere as well as the resulting dynamic process in the melt pool and the work piece material, respectively. These process-related discontinuities have an influence on the yield and fracture behavior in local stress concentrations caused by different notches. Therefore, the influence of local stress concentrations caused by different notches on the fracture and yield behavior is studied for different heat treatment states. The results have shown that the examined heat-treatment conditions for the considered notches do not show “notch weakening.”
