Question

Differance between plastic deformation and severe plastic deformation

Answer 1

Explanation:

Severe plastic deformation (SPD) is a generic term describing a group of

metalworking techniques involving very large strains typically involving a complex stress state or high shear, resulting in a high defect density and equiaxed "ultrafine" grain (UFG) size (d < 500 nm) or nanocrystalline (NC) structure (d < 100 nm).[1]
