Abstract

The paper presents some scientific results referring to Commercially Ti Grade 2 processed by SPD (Severe Plastic Deformation) to reach nanometric scale. Accumulative Roll Bonding (ARB) procedure offers the possibility to refine the grain in bulk material and therefore the sensible improvement of mechanical properties of the metallic materials utilized in practical applications. The scientific research is focused on ARB process settlement. Also, structural analysis and mechanical tests were made on processed material.The results regarding the possibility to obtain structures in UFG (Ultra Fine Grain) range or NC (Nanocrystalline Grains) range confirm that, in the case of Commercial Ti Grade 2, the use of SPD techniques, more precisely ARB (Accumulative Roll Bonding), leads to structures placed in UFG domain (0.780 μm)..

Keywords
