This assignment delves into the analysis of selective laser melting (SLM) of the titanium alloy Ti-6Al-4V. It explores the impact of various heat treatments, including stress relieving and alpha-beta annealing, on the mechanical properties like tensile strength and hardness. The study investigates the microstructure evolution and the role of porosity in influencing the overall performance of SLM-fabricated Ti-6Al-4V components.
