OBJECTIVE
The knowledge of thermodynamics is the basic requirement for understanding various
alloy systems, phase transformations and interpreting properties. It also covers kinetics
of reactions as well as heat and mass transfer in different systems.
UNIT I INTRODUCTION TO THERMODYNAMICS 8
Definition of thermodynamic terms; concept of states, systems, equilibrium. Equation of
states, extensive and intensive properties, homogeneous and heterogeneous systems.
Phase diagram of a single component system. Internal energy, heat capacity, enthalpy,
UNIT II LAWS OF THERMODYNAMICS 10
The Second law of thermodynamics, entropy degree of reversibility and irreversibility,
criteria of equilibrium, auxiliary functions, combined statements, Maxwell's relations,
transformation formula, Gibbs-Helmoltz equation. Concept of Third law, temperature
dependence of entropy, statistical interpretation of entropy, Deby and Einstein concept
of heat capacity, relation between Cp and Cv, Consequences of third law.
UNIT III THERMODYNAMICS OF REACTIONS 10
Solutions, partial molal quantities, ideal and non-ideal solutions, Henry's law, Gibbs -
Duhem equation, regular solution, quasi-chemical approach to solution, statistical
treatment. Change of standard state. Phase relations and phase rule-its applications.
Free energy composition diagrams for binary alloy systems, determination of liquidus,
solidus and solvus lines. Effect of pressure on phase transformation and phase
24
equilibria. Thermodynamics of electrochemical cells, solid electrolytes. Thermodynamics
of point defects in solids.
UNIT IV INTRODUCTION TO METALLURGICAL KINETICS 10
Heterogeneous reaction kinetics-gas-solid, solid-liquid, liquid-liquid and solid-solid
systems. Solid state diffusion- Ficks law, mechanism of diffusion, uphill diffusion,
kirkendall effect, steady an transient diffusion, external mass transfer – fluid flow and its
relevance to mass transfer, general mass transport equation, concept of mass transfer
coefficient, models of mass transfer- film theory and Higbie’s penetration theory, Internal
mass transfer- ordinary and Knudsen diffusion, mass transfer with reaction, adsorptionphysical
UNIT V ELETROCHEMICAL KINETICS 7
Concept of polarization, activation over potential, Butler-Volmer and Tafel’s equation,
applications in Electrodeposition and corrosion, concentration over potential, limiting
current, electro-winning and corrosion
