“…There are a few data in the literature on the chemical composition of hydrides formed in titanium alloys. Some authors 6 observed formation of complex hydrides with similar structures such as TiH 2 –3AlH 3 . Moreover, the new phases could be precipitated from the system when hydrogen reaches a certain level.…”

6Al-4V alloy were produced via the powder metallurgy technique applying the hydride-dehydride process and hot isostatic pressing. The conditions of reversible hydridedehydride process were controlled by chemical and X-ray diffraction analysis and scanning electron microscopy. Powders were pressed above and below the aRb transus temperature. The presence of titanium hydrides and morphology of the microstructure have the direct influence on the tensile properties and fracture toughness of the Ti-6Al-4V alloy, but the effect of microstructure is more pronounced.

“…Moreover, the new phases could be precipitated from the system when hydrogen reaches a certain level. 6 Hydrides detected as a function of thermal treatment and H/D processing parameters are shown in Table 2. Apart traces of titanium hydride (TiH 2 ), traces of titanium nitride (TiN) and vanadium hydride (VH) were also observed.…”

“…It is very commonly used in aerospace, automotive, and medical industries, due to its high strength/weight ratio, corrosion resistance, biocompatibility, and low thermal expansion characteristics. Although Ti6Al4V alloy is a high-cost material it has a loss of about 70-80% as scrap while manufacturing of engineering components [3]. Owing to the high oxygen affinity, recovery of titanium-based scraps by re-melting is a difficult and costly process.…”

Abstract:The objective of this research is for Ti6Al4V alloy turnings, generated during the machining of implants, to produce powders for the fabrication of Ti base coating via the cold spray method. In order to decrease the cost of powder production and increase the recycling rate of the turnings, the hydrogenation-dehydrogenation (HDH) process has been utilised. The HDH process consists of the following sequence: surface conditioning of the turnings, hydrogenation, ball milling (for powder production), and dehydrogenation. Afterwards, the properties of the recycled powder were analysed via phase, chemical, and morphological examinations, and size and flowability measurements. Usability of the powder in additive manufacturing applications has been evaluated via examining the characteristics of the deposit produced from this powder by the cold spray method. In short, promising results were obtained regarding the potential of the recycled powders in additive manufacturing after making minor adjustments in the HDH process.
