Abstract: This paper addresses the optimal manufacture of titanium alloy composites via inductive hot pressing, and studies the influence of nanosized reinforcement and matrix powders on the final properties of the titanium-based composites. Before hot consolidation, two types of Ti-6Al-4V powders were mixed with various percentages of nano-diamonds. After inductive hot pressing at 900°C and 950°C, characterisation of the specimens took place, which revealed significant differences in the final properties of the composites produced. Further to the well-known effect of how oxygen content in the initial powder considerably affects the properties of the specimens, the influence of the nano-diamonds in the microstructure is also evaluated.
