Severe Plastic Deformation

It has been already well established that the nanostructured materials(materials with a grain size of 100mm or less) is the future materials.Nanostructured materials possess properties superior to those ofconventional, coarse grained materials. Hence designing potentiallycost efficient and environmentally friendly products with betterperformance is a possibility. Among others, nanostructured materialsexhibit increased strength, hardness and ductility and provide anopportunity for superplastic forming. When all the procedures in use forthe production of nanostructured materials are examined, only severeplastic deformation (SPD) processes exhibit a potential for producingrelatively large samples suitable for industrial applications.
