The large deformation at cryogenic temperature would be one of the effective methods to produce large bulk UFG materials.
Introduction Recently, ultrafine grained (UFG) materials with grain size less than 1-m have been studied extensively, since they are expected to provide high strength without the degradation of toughness.
Earlier works have shown that severe plastic deformation (SPD) techniques, such as equal channel angular pressing (ECAP), accumulative roll bonding (ARB), multiple compression and severe torsional straining (STS), etc. are effective in manufacturing UFG materials [1-5].
Among those processes, the large deformation at cryogenic temperature would be one of the effective methods to produce large bulk UFG materials.

By creating a moving local hot spot around the contact point between tool and sheet, process forces can be reduced while forming limits are increased for most materials.
Secondly a brief overview is given on the material of choice for this study.
Material: The material of choice is AA 5182-O, containing 4.5 wt% Mg and 0.35wt% Mn.
This could be due to the buildup of material on the tool.
Also special recognition goes to the Flemish agency for innovation by science and technology IWT for its support through ISF Light.

Generally, in steel turning, increasing in material removal rate, decreases surface finishing and vise versa.
Therefore, when the weight of material removal rate is 1 and the weight of surface roughness is 0 then, the material removal rate will be maximum and visa versa.
