Abstract

The thermodynamic theory of the deformation of heterophase solids containing polydomain phases is presented. The polydomain phases consisting of twins are considered. Elastic interaction between twins leads to the formation of an equilibrium polydomain structure. Its basic element is a polytwin: a plane-parallel plate consisting of alternating plane-parallel twins. In a uniform single crystal the polytwin structure is unstable and should disappear at any uniform external stress. But it can be stable in a heterophase system. The evolution of the equilibrium structure with the variation of the external stress exhibits reversible superplasticity and pseudoelasticity. Two contributions into total strain are considered: due to displacements of twin boundaries inside a polydomain (polytwin) phase and due to movement of interfaces between polydomain and matrix phases.
