Investigation of microstructure and mechanical properties of commercially pure aluminum produced by RCS process

Severe plastic deformation (SPD) process is capable of developing the submicron grain structures in metallic alloys and to improve the Mechanical properties. Repetitive corrugation and straightening (RCS) processes are widely used in industries to compensate the high strength metal plates components used in automobiles. In the present work an attempt has been made to study the influence of RCS parameters like strain rate, number of passes and plate thickness to predict the degree of importance on grain size, micro hardness and tensile strength of RCS specimens. The results indicated that the number of passes has a major influence on the fine-grain refinement, followed by Al plate thickness and strain rate
