INTRODUCTION

BULK nanostructured materials (BNMs)/ultra-fine grained (UFG) materials are new-generation materials that have excellent room temperature mechanical properties. It is well known from Hall–Petch relationship that a reduction in grain size improves strength and hardness and the grain sizes are of the order of
