What is Ti6Al4V?

Ti6Al4V Titanium is a high-strength, low-density Ti alloy known for its excellent corrosion resistance. 6k Additive's Ti6Al4V spherical metal powders deliver excellent material properties that enable AM 3d metal print designers to take advantage of design freedom of additive manufacturing Titanium metal powder. Ti-6Al-4V, sometimes called TC4 or Ti64, is an alpha-beta titanium alloy with a high strength-to-weight ratio. It is applied in many applications where low density, aerospace industry and biomechanical applications (implants and prostheses). The powder can be used in laser beam additive manufacturing, powder metallurgy, spraying, and other processes. The powder can be used in the manufacture of aerospace parts, repair work aero engine blades, and medical equipment. The powder used in various types of metal 3D printers, including Renishaw from the UK, EOS from Germany, Concept Laser, 3D systems from the United States, and many other laser melting equipment. This work investigates the effects of powder characteristics, particularly particle size distribution (PSD), on the micro-/defect-structure, tensile, and fatigue properties of Grade 23 Ti-6Al-4V specimens, as well as how these effects are influenced by the build location and specimens' surface finish. Two batches of plasma atomized Ti-6Al-4V powder feedstock with two different PSDs of 15–45 µm (fine) and 15–53 µm (coarse) were used for fabrication. Both batches exhibited excellent rheological properties, with moderate improvement noted in the fine batch. The influence of PSDs was small on the resulting microstructure and surface roughness of the specimens while significant on the volumetric defect distribution. In addition, machined specimens fabricated from coarse powder exhibited somewhat enhanced ductility, smaller defects, and some improvements in fatigue properties compared to fine powder specimens. These variations were correlated with the lower tendency of spattering in coarse powder. Process-induced silicon-rich spatters, detrimental to both tensile and fatigue properties, were more prevalent in the specimens built from the fine powder batch and were ascribed to the rapid decomposition of SiO2. Due to the highly spherical particles and the excellent flowability of both batches, defect content, and mechanical properties did not show strong location dependency.
