Conventional coarse grained (CG) commercial pure (CP) Ti Grade 2 was studied after cold rolling (CR) at room temperature, and after equal channel angular pressing (ECAP) at 450 degrees C followed by CR, by transmission electron microscopy (TEM) methods. CR of the CG material leads to a microstructure showing initially twins with (01(1) over bar 2) type and later subgrains separated by low-angle grain boundaries. CR carried out after ECAP yields the fragmentation of fine grains (300 - 800 nm) mostly bounded by high-angle boundaries into elongated subgrains (similar to 100 nm). It was shown with in-situ annealing experiments in the TEM that this microstructure is thermally stable up to a temperature of 450 degrees C. Tensile tests showed that the combination of ECAP with CR has the potential to produce at the same time high strength (941 MPa) and high ductility (16.7%).
