N2 - Commercially pure titanium was subjected to hydrostatic extrusion resulting in formation of an ultra-fine grained microstructure with a strong ¡-fiber texture and significant improvement of mechanical strength. Anisotropy of the tensile and fracture behavior of the hydrostatically extruded material was studied. It will be demonstrated that the material has significantly higher yield strength along the extrusion direction, while in transversal direction it shows higher work hardening ability related to the ¡-fiber crystallographic texture. The anisotropy of the fracture behavior in these two directions is less pronounced. A slightly lower fracture initiation toughness and crack growth resistance along the extrusion axis can be related to a lower crack propagation resistance along the boundaries of the elongated grains.
