The beta titanium alloys are widely used for hard tissue replacements due to their properties (e.g. high strength, low Young’s modulus or biocompatibility). Mechanical properties are dependent on microstructure which can be controlled through suitable thermo-mechanical treatment. The effect of cold rolling on texture evolution and mechanical properties has been studied in this paper. Hot forged, solution treated ( / 0.5 h / water quenched) Ti-35Nb-6Ta alloy has been cold rolled with thickness reduction 40, 60 and 80 and 95%. The texture evolution has been studied by using X-ray diffraction analysis and EBSD analysis. The {100} <110> texture is dominant for all studied specimens and became more distinct with increasing thickness reduction. Another texture evolution from {211} <110> to {111} <112> was observed with increasing thickness reduction. The tensile strength increased with thickness reduction from 600 to 830 MPa. On the other hand elongation decreased from 32 to 9%. The Young’s modulus value has been determined within range of 43 to 55 GPa.
