The austenitic stainless steel (SS) has been used as a material for building ultra high vacuum (UHV) chamber. Recently significant efforts have been concerned a comparing the standard cleaned for ultra high vacuum, passivity stainless. In this work Austenitic nanocomposites were synthesize by sol- gel method. The morphologies and topographies of the samples have been studied with using Scanning Electron Microscopy (SEM) and X-Ray diffraction (XRD) Techniques. The principal aim is the Nanostructural evolution of these samples. The obtained results indicate that adding 10.8 gr Ni particles into SS matrix,modified SS device mechanical structures.
