Microstructure and Mechanical Properties of Metals and Alloys Deformed in Liquid Nitrogen: Review

The goal of a given review is to consider the main directions to modify the structure and mechanical properties in the bulk and on the surface of metals and alloys via the severe plastic deformation at the liquid-nitrogen temperature. Investigations of the effect of such a type of the cryodeformation on the processes of nanostructuring as well as the characteristics of the metallicmaterials’ strength and ductility with different crystal lattices and the stacking fault energies are resulted. The possibility to achieve an optimal combination of both strength and ductility by the cryodeformation and subsequent annealing is shown.
