Abstract: The research aims to optimize the Ti6Al4V implants with mechanical properties matching that of human bones. Powder metallurgy processes were used to generate the alloy by the field assisted sintering technique combined with rapid cooling. It could be proven that the rapid cooling has an important effect on the microstructures, while maintaining the nanostructures of the raw materials. This allowed to improve the mechanical properties of the sintered alloys. Porous structures are designed to achieve implants with low elastic modulus to improve the fixation between the bone and the implants.
