摘要

Abstract

BSTRACTIt is shown by finite element modeling that under high-pressure torsion of water-atomized pure iron powder a zone with high shear strain and high density develops first in a layer adjacent to the moving anvil. The finite element simulation results and an analytical calculation using the minimum plastic energy extremum principle both show that with further deformation the compacted zone extends progressively in the radial and axial directions throughout the specimen.
