Study of Structural Evaluation and Mechanical properties of IF Steel and Aluminium sheets processes by ARB process

In recent years research on the processing, structure and mechanical behavior of nanocrystalline (d < 100 nm) and ultra-fine grained (100<d<1 lm) materials has thrived[1]. Both the promising structural properties, such as elevated strength, good wear resistance and high tough-ness, as well as the potential for superplasticity at low temperatures and high strain rates [2,3], constitute the driving force for this flourshing field. Processing homog-eneous bulk nano and ultra-fine grained (ufg) structures is complex endeavor.
