Study of severe plastic deformations of metallic materials:- A move towards Amorphization

Abstract

This review highlights one of the amorphization processes of metals, alloys as well as metal matrix composites (MMCs) and its benefits towards strength enhancements. The need for material properties such as low weight, improved strength, enhanced wear, and corrosion resistance along with sensible ductility instigated the researchers to investigate the effect of different reinforcements as well as processing techniques on light metals. Developments in different primary, as well as secondary processing techniques, partly resulted in the enhancement of material properties. Different severe plastic deformation (SPD) technologies consequence the formation of ultra-fine grain structures as well as even nano-crystalline materials hence resulting in alteration of material properties. The numerous techniques are high-pressure torsion (HPT), accumulative roll bonding (ARB), equal channel angular pressing (ECAP), repetitive corrugation and straightening (RCS), etc. The operational principles of different SPDs, microstructural revolutions, mechanical properties are reported here. Implementation of the SPD techniques for the property enhancement of aluminium matrix composites (AMC) is the limelight here. Furthermore, this article highlights the recent achievements and current developments in determining the deformation mechanisms.
