Abstract
The behavior of pure metals and alloys are studied during the shear deformation in Bridgman anvils under a high quasi-hydrostatic pressure. Structural evolution is estimated from the change of the torque detected continuously during deformation. It is shown that a comparison of the dependence of the torque on the number of anvil revolutions obtained for a certain material with the reference curve of a pure metal can be successfully used to detect the structure-phase transformations during severe plastic deformation.
