ABSTRACT
Mechanochemistry studies the effect of non-hydrostatic stresses and plastic strains on various structural changes (SCs), which include solid–solid, solid–liquid, and solid–gas chemical reactions and phase transitions. This chapter describes the general theory of SC in inelastic materials, and analyzes some analytical solutions based on our theory and their application to some real situations. It discusses a new multiscale theory of strain-induced SCs under high pressure and applied to interpret the numerous phenomena which occur during compression and shear of materials in a rotational diamond anvil cell. For inelastic materials, J. R. Patel and M. Cohen suggested maximizing the mechanical work in order to choose the appropriate habit-plane variant. The most fundamental results in strain-induced SCs were obtained in rotating Bridgman or diamond anvils. Earlierthe possibility of semicoherent SC in elastic materials was estimated by comparing the energy of a coherent nucleus and a semicoherent nucleus while taking into account the energy of the dislocations.
