Hydrostatic extrusion (HE), which belongs to the severe plastic deformation (SPD) techniques, permits producing titanium with a nano-crystalline structure. The homogeneity of the microstructure, the volume of the product and also the quality of its surface depend on the parameters of the hydrostatic extrusion process. The study was concerned with the effects of the deformation magnitude and the number of the HE cycles upon the microstructure and mechanical properties of the titanium being treated. The course of the HE process and its final product appeared to depend greatly on the process temperature and the starting state of the titanium surface. The results obtained during the experiments permitted optimizing the HE process, and improving the performance and mechanical properties of the final product.
