Thermal effects in mechanochemistry

Abstract

Fundamental thermodynamic equations are presented for anisotropic bodies with account forthermal effects. Definitions for Gibbs energy, partial molar quantities with respect to a direction chosen inan anisotropic phase, as well as expressions for the chemical potential tensor of an immobile component of asolid and for the chemical affinity tensor for a physicochemical process (including chemical reactions) in terms of the strain tensor variables and mixed variables including one component of the stress tensor are proposed. Conditions of stationary affinity and phase equilibrium are deduced. The mechanochemistry of polymorphous transformations is formulated for the cases of first- and second-order phase transitions.
