Ti6Al4V (pronounced Ti-64), is a titanium alloy used in a variety of engineering applications including the aerospace, automotive, and biomedical industries. Ti6Al4V is made up of a combined ɑ-β microstructure, which provides it with many valuable properties such as high strength, low weight, high melting point, corrosion resistance, and biocompatibility. [1] For years, casting and forging have been the traditional processes used for the manufacturing of Ti6Al4V components, but recent interest in the additive manufacturing of Ti6Al4V through the Electron Beam Melting (EBM), Selective Laser Melting (SLM), and Directed Energy Deposition (DED) methods has been gained. The goal of this paper is to provide each author and reader with an understanding of the Ti6Al4V alloy, by encompassing the characteristics of Ti6Al4V into a process-structure-property-performance (PSPP) map. This will be accomplished by reviewing a growing body of literature related to Ti6Al4V. Also, a comparative analysis of the traditional manufacturing and additive manufacturing of Ti6Al4V will be performed, while exploring the benefits and limitations of both.
