Severe plastic deformation by cold rolling after multi-directional forging in commercially pure titanium is carried out. Mechanical properties are evaluated by hardness test and tensile test. Specimens cold-rolled after multi-directional forging can have a higher hardness than specimens that have only been multi-directional forged and cold-rolled. The tensile strength of specimens both only cold-rolled and cold-rolled after multi-directional forging increases with the increase in cumulative plastic strain. The elongation decreases with increase in the rolling reduction of cold rolling.
