Abstract: In this thesis, the research works are being divided into two parts. First part of the work will detail the variation and adjustment of selective laser melting parameters to achieve the lowest possible porosity. Two different characterization techniques consist of Archimedes method and X-ray Micro-CT were used to quantify the amount of density and porosity in the specimens. Experimental results show that 99.9% density was achievable with two of the printing parameters. The subsequent post heat treatment process with hot isostatic pressing was able to further improve the density level to be comparable to wrought specimen. The second part of the work will detail the variation of post heat treatment profiles in terms of temperature and duration to see if there are improvement in microstructure and mechanical properties over the as printed SLM condition and how well it compare to wrought specimen.
