Powders with irregular morphology can be transformed into highly spherical powders with a better physical and mechanical properties and as such have applications in additive technologies. Due to its corrosion resistance and biocompatibility, the TiAl6Nb7 alloy is one of the most suitable materials for medical applications, such as implants, instruments, etc. The chemical properties of this alloy enable the use of HDH technology as an economical process for producing ‘low-cost’ high-value powders based on titanium alloys. This paper presents the quality of a hydrated titanium powder sample after thermochemical treatment in a furnace under a hydrogen atmosphere, which enabled the achievement of the desired brittleness. The results of SEM/EDS analysis of the hydrated powder of the titanium alloy TiAl6Nb7 showed the presence of two specific phases with different chemical compositions. It can be concluded that the concentration of certain elements, particularly niobium, contributes to the formation of the Ti hydride phase and increases the brittleness of the TiAl6Nb7 alloy at room temperature, which is advantageous from the aspect of grinding the alloy. During the grinding process, titanium alloy powder with unchanged chemical composition, with irregular particle shape, is obtained. Powders with irregular morphology can be transformed into highly spherical powders with improved physical and mechanical properties, making them suitable for applications in additive manufacturing technologies.
