X-Ray CT Investigation of Graded Ti-Ti64 Material Produced by Selective Laser Melting

Abstract:

This paper is devoted to the study of gradient samples of Ti-Ti64 material, manufactured by selective laser melting. The measurements of porosity, differences in densities are made with x-ray computed tomography for as-processed and after hot isostatic pressing samples. The raw data was processed using the software Volume Graphics and AVIZO. The porosity of the samples was studied and their sphericity was calculated.
