Study of pore defect and mechanical properties in selective laser melted Ti6Al4V alloy based on X-ray computed tomography

The selective laser melting (SLM) technology is widely used for the manufacturing of Ti6Al4V alloy components in the biomedical and aerospace industries, and the residual pores are one of the significant defects obstructing its further application. X-ray computed tomography (XCT) technique was applied for the examination and analysis of the spatial and morphological features of pore defects, which will influence the tensile properties of the...
