Abstract

The Ti6Al4V alloys are finding various industrial applications due to their attractive attributes, which can be enhanced via heat-treatment processes. In this study, titanium sheets (Ti6Al4V) were manufactured through laser metal deposition (LMD) using Ti6Al4V powder of particle sizes between 45-90 µm. The build parameters used are optimized at a laser power of 400 W, powder feed rate of 2.4 g/min, hatch spacing of 0.9652 mm, and scanning rotated at 90° between successive layers. The built block is sliced using a wire-electric discharge machine (EDM) into sheets of 2 mm thickness. The resulting blocks were joined using the butt configuration through laser beam welding technology. Post-weld heat treatments were conducted on the welds above the β transus temperature of 995°C. Material characterizations of the evolving properties were conducted using Optical Microscopy, Vickers microhardness, and tensile testing. The investigations show that the heat-treated samples have enhanced properties and can be recommended. The outcome of this research is significant as it gives insight into the optimization of laser welding and post-weld heat treatment parameters of Titanium Alloy Grade 5 for industrial applications.
