MECHANOCHEMISTRY OF MATERIALS

Considerable advances have been made in mechanochemistry in the last couple of decades. Training of experts in this field with a background in materials science, chemical and mechanical engineering, etc. requires study of the fundamentals of mechanochemistry. There is a need for a textbook in the general and compressed form which would cover many aspects and would be used as a basis for understanding the fundamental principles to control mechanochemical phenomena. This textbook is based on lectures given by Prof Gutman in a graduate course in the mechanochemistry of materials at the Ben-Gurion University of the Negev. The book contains examples of experimental results to illustrate the mechanochemical phenomena and technologies.

Contents:
What is mechanochemistry of materials? Basic features of the behaviour of solids relevant to mechanochemical processes (thermodynamics of solids, surface phenomena, chemical kinetics, etc.) Irreversible thermodynamics of mechanochemical reactions (mechanochemical activity of substances, chemical potential of dislocations and its effect on the chemical potential of solids, irreversible cooperative processes of chemical reaction, plastic deformation and dispersion of solids, entropy generation, chemomechanical effect, etc.) Kinetics of mechanochemical reactions under different stress state conditions (hydrostatic stress state, plastic deformation, dynamic loading and relaxation, fine grinding and comminution, ultrasonic irradiation, explosive shock waves, etc.) Main types of heterogeneous mechanochemical reactions (dissolution, dissociation, extractive processes, solid state reactions, synthesis of organic and inorganic compounds, mechanical alloying, polymer stress reactions, electrochemistry, stress corrosion, tribochemistry, wear) Mechanoelectrical phenomena and mechanoemission (mechanically stimulated electric charging processes, mechanoemission and mechanoluminescence, etc.) Application of mechanochemistry in materials engineering (materials production, carbides, silicates, superconductors, polymers, ceramics, materials treatment and processing, etc.) .
