Effect of the fraction and direction of high-pressure torsion deformation in a Bridgman cell on the structure and mechanical properties of commercial-purity iron

The effect of the fraction and the scheme of deformation under high quasi-hydrostatic pressure in a Bridgman cell at room temperature and on the structure and the microhardness of commercial-purity iron is studied.

Summary:The effect of the fraction and the scheme of deformation under high quasi-hydrostatic pressure in a Bridgman cell at room temperature and on the structure and the microhardness of commercial-purity iron is studied. Deformation is performed by one continuous or portioned loading to the same total strain. The number of cycles and the direction of rotation of the lower movable anvil are varied. It is determined that the number of revolutions and the direction of rotation considerably affect the sizes of the deformation-induced fragments and the recrystallized grains formed upon megaplastic deformation. The correlation between the structure parameters and the microhardness is analyzed.
