Abstract
In most manufacturing processes, objects of the required
shape and size are produced through plastic deformation; sometimes
by deforming the product itself through rolling, extrusion, drawing
etc, and by deforming the metal removed through grinding, milling
and cutting operation. In these processes, a load of appreciable
magnitude is applied on the material subjected to deformation, and
the plastic flow thus produced is suitably restricted to get the desired
shape and size. Equal Channel Angular Pressing (ECAP) is very
capable of producing ultrafine grained microstructures and improves
the mechanical properties of the deformed materials. The variations
in strain path directions during deformation have significantly effect
on the physical and mechanical response of distorted metals.
