摘要

This comprehensive review focuses on the additive manufacturing (AM) of Ti6Al4V, a high-density titanium alloy valued for its strength, biocompatibility, and corrosion resistance. With applications ranging from aerospace to power plants, traditional manufacturing processes generate significant material waste and prolonged production times. The review examines about AM such as DED (directed energy deposition), SLM (selective laser melting), and EBM (electron beam melting), highlighting their capabilities in producing complex geometries directly from raw materials. Thermal behavior analysis and microstructural analysis explore the influence of manufacturing processes on phase formation and grain structures. Insights into the evolution of grain size and microstructure coarsening offer valuable understanding of how material properties are influenced by input energy density. Tensile and fatigue characteristics are discussed, providing comparisons with traditional manufacturing methods. In summary, the review aims to contribute valuable insights for optimizing AM processes and enhancing material properties for Ti6Al4V applications.
