Severe plastic deformation (SPD) is known to be the best method for producing bulk ultrafine grained and nanostructured materials with excellent properties. Different Severe Plastic deformation occurs through crystal distortion localized to slip planes and directions, most commonly through translational glide of dislocations. The presence of defects like dislocations These methods exhibit major differences in the experimental set up and the processing of the measured force and displacement curves, thus affecting the material
