摘要
The formation of nanostructures in metallic materials by severe plastic deformation (SPD) was studied to obtain information on the high strength and fatigue properties of metals and alloys for structural applications. Two SPD techniques were applied most intensively for a structure refinement up to nanometer sizes, namely, equal-channel angular (ECA) pressing and high pressure torsion (HPT). The ultrafine grained nanostructures were successfully processed by SPD via ECA pressing, but the type of the as-fabricated nanostructures depends essentially on the processing regimes. Significant improvement of fatigue and strength were shown by the ECA-pressed nanostructured commercially pure titanium.
