Abstract
A method of producing a nano twinned commercially pure titanium material includes the step of casting a commercially pure titanium material, that apart from titanium, contains not more than 0.05 wt % N; not more than 0.08 wt % C; not more than 0.015 wt % H; not more than 0.50 wt % Fe; not more than 0.40 wt % O; and not more than 0.40 wt % residuals. The material is brought to a temperature at or below 0° C. and plastic deformation is imparted to the material at that temperature to such a degree that nano twins are formed in the material.
