Assessment of Severe Plastic Deformation Processes in Bulk and Nanostructured Metallic Glass

The metallic glasses are known as amorphous and metastable materials. These materials have superior mechanical properties over crystalline with the same chemistry. Continuous efforts were made to improve of glass. severe plastic deformation (SPD) method is used ductility SPD causes at atomic level in disordered structure Many methods reported, such cryogenic cycling, high-pressure torsion, equal channel angular pressing, which for SPD. In recent works on nanostructured glasses, it has been evidenced that some properties, example, mechanical, thermal, magnetic, improved compared bulk This paper reviewed progress glasses. Different addressed here. effect glass deliberated this paper. Moreover, challenging tasks occurrence its characterization considered, trying develop a sound understanding
