Laser Powder Bed Fusion of Ti-6Al-4 V Alloys for the Production of Defect-Free AM Parts: A Recent Update

Titanium alloy is a material of choice when it comes to applications requiring high-performing mechanical properties, lightweight structure, superior biocompatibility, and excellent corrosion resistance properties. In recent times, laser powder bed fusion (L-PBF) has been widely regarded as one of the most frequently studied additive manufacturing techniques utilizing titanium alloys for the manufacturing of parts in industrial sectors. In this review article, the significant influence of process parameters on the improvement of mechanical and microstructure properties for the development of defect-free L-PBF-processed Ti-6Al-4 V components, the effect of post-processing manufacturing techniques to control the internal defects, its key future directions, and the challenges limiting its adoption for practical application in industries have been properly identified and discussed.
