The evolution of microstructure and the mechanical properties of equal channel angular pressing (ECAP) processed materials depend on the plastic deformation behavior during ECAP, which is governed mainly by the die geometry, the constitutive behavior of the material itself and the processing conditi
Many unusual properties of ultrafine grain materials obtained by equal channel angular pressing (ECAP) are commonly attributed to non-equilibrium grain boundaries. Such grain boundaries are expected to exhibit higher values of energy, higher amplitude of strain fields, a larger free volume and a hig
