Abstract Scope |
Process-induced volumetric defects are inherent to additively manufactured parts. This study investigates the effect of volumetric defects on the tensile properties of the laser powder bed fusion (L-PBF) Ti-6Al-4V specimens fabricated with large variations in process parameters (a total of six sets of process parameters). Cylindrical bars of L-PBF Ti-6Al-4V specimens are stress-relieved before removal from plates and machined to tensile specimens. The defect distribution of specimens resulting from each set of process parameters is analyzed using a high-resolution X-ray Computed Tomography machine. Quasi-static tensile tests are performed at room temperature. A scanning electron microscope is used to conduct fractography. Tensile results are correlated with defect statistics and identified features on fracture surfaces. |
