Severe Plastic Deformation Technologies for Ultra Fine Grained Alloys


Article Preview

Some of new severe plastic deformation processes as equal channel angular extrusion, and strip shearing are presented as very efficient techniques for grain refinement. Channel geometry, contact friction, strain rate and multi-pass processing versus microstructure and mechanical properties are shown.
