... to 35.25 GPa. Five TPMS solid gyroid samples made of Ti-6Al-4V were designed for a specific stiffness corresponding to the bone, using an analytical model considering an exponential relationship between stiffness and porosity. These structures were then manufactured through selective laser melting...

... microstructure during AM of Ti-6Al-4V. Temperature gradient and solidification rate are the factors that control the target solidification structure, i.e., columnar to equiaxed transition (CET) of grains, to achieve desired mechanical properties. A multi-track finite element model is established and validated...

X-ray computed tomography (XCT) and X-ray diffraction (XRD) were...

... Abstract Ti-6Al-4V is an alpha-beta titanium alloy having excellent strength, low modulus of elasticity, high corrosion resistance, good weldability and heat treatability. Consequently, it is the most commonly used titanium alloy with a wide use for applications in aerospace, automotive...

... Abstract Ti-6Al-4V is the most commonly used titanium alloy in aerospace, automotive, and biomedical industries because of its excellent strength, low modulus of elasticity, high corrosion resistance, good weldability and heat treatability. In this study, numerical investigation is conducted...

... Abstract Additive manufacturing techniques have made AM Ti-6Al-4V parts a reality in many industries. However, despite the optimism, their poor fatigue performance especially in high cycle regime is the major hurdle for the industry accepting it as mainstream. One of the reasons owes...

... Abstract Titanium (Ti) alloys are classified as difficult-to-machine materials due to low thermal conductivity, low modulus, and high chemical reactivity. In this paper, a Ti-6Al-4V alloy bar in a solution treated and aged (STA) microstructure is turned using uncoated carbide, two commercial...

.... This will be presented for two different materials Nimonic 90 and Ti-6Al-4V. For Nimonic 90 a built-up-edge (BUE) will be identified, and this is based on the stream-line inflow-angle. Quite contrary is the chip formation process for Ti-6Al-4V. A diffusion process in the interface chip-tool take place resulting...

... Abstract In cutting of Ti-6Al-4V alloy, the cutting speed is limited since a high cutting temperature leads to severe tool wear and short tool life, resulting in poor production efficiency. On the other hand, some recent literature has reported that various beneficial effects can be provided...

... the feasibility of pore generation and to characterize the pores and examine the effect from various process conditions. The pore-generated specimens were fabricated in an L-PBF system using Ti-6Al-4V (Ti64) powder. Overall, specimens were made using default settings. But, during processing the middle section...

... are deposited on semi-cylindrical samples with Ti-6Al-4V powder particles for three levels of power and speed combinations. The single tracks are built at a certain height from the base plate instead of on the build plate to include the effect of the powder particles. The experiment includes single tracks...

... rate and surface quality for Ti-6Al-4V were investigated. Corrosion processing rate depends upon hydrofluoric acid concentration, the volume ratio of nitric acid to hydrofluoric acid, temperature. Nitric acid can promote the surface passivation and reduce surface roughness. The surfactant plays a dual...
