The activation energy of twinning for copper in Voigt approximation
The formation of twins can significantly affect the plasticity and strength of materials. The possibility of applying the two-component model of single-phase hybrid materials to explain anomalous temperature dependence of elasticity moduli of copper with a submicrocrystalline structure has been disc...

| description | The formation of twins can significantly affect the plasticity and strength of materials. The possibility of applying the two-component model of single-phase hybrid materials to explain anomalous temperature dependence of elasticity moduli of copper with a submicrocrystalline structure has been discussed. An analysis has been performed that is based on previously existing experimental data. A twinning mechanism of changing the crystallite orientation has been proposed. Master Twinning Curve (MTC) is proposed to obtain the twinning activation energy. The apparent activation energies for the MTC are determined by minimising mean residual squares (MRS) method. The activation energy for twinning in copper characterized by an ultrafine-grained (nano- and submicroscopic) structure is found in Voigt approximation to be 0.123 eV.
