JNTUK B.Tech Metallurgical Thermodynamics gives you detail information of Metallurgical Thermodynamics R13 syllabus It will be help full to understand you complete curriculum of the year.
Course Objective: To apply knowledge of maths, science and Engineering to understand the application of the thermodynamics for diffusion, thermal properties, solutions, phase diagrams and reversible cell studies.
UNIT-I : Learning objective: To understand the basic concepts of diffusion with a detailed theoretical and experimental study of diffusion mechanisms in metals and alloys.
Diffusion: Ficks law of diffusion and its application, Kirkendal effect. Darken’s equation, the Metano method, Determination of intrinsic diffusivities, Self-diffusion in pure metals, Temperature dependence of the diffusion coefficient, diffusion along the grain boundaries and surfaces. Problems.
UNIT-II : Learning objective: To understand the importance of Ellingham diagrams in metal extraction processes. Ellingham diagrams: Introduction, calculation of equilibrium constants from standard free energy changes, general description of Ellingham diagrams, Interpretation of two or more free energy change Vs. temperature lines taken together, derivation and uses of the oxygen, nomographic scale in Richardsons diagrams.
UNIT-III : Learning objective: To study and evaluate thermal properties of solids.
Thermal properties: Specific heats of solids, classical, Einstein and Debyees’ Model of the lattice, Specific heat of solids, Anhamaonicity, thermal expansion, thermal conductivity of solids, lattice thermal conductivity and thermo-electric effects. Stability of crystal disorders.
UNIT-IV : Learning objective: To understand the basic thermodynamic concepts of solutions with their applications. Solutions: Composition, partial molal quantities, ideal solutions, Raoults Law, actual (Nonideal) solutions, Sieverts law, Gibb’s – Duhem equation, integration of Gibbs’ – Duhem equation, Excess thermodynamics quantitie
UNIT-V : Learning objective: To apply thermodynamic concepts for the study of phase diagrams.
Application to phase diagrams: concept of chemical potential, equality of chemical potentials in equilibrated phases derivation of Gibb’s phase rule, solidus and liquidus lines for an ideal solution, calculation of liquidus line for eutectic systems
UNIT-VI : Learning objective: To understand the application of thermodynamics for the study of electro chemical cells. Reversible cells: Electro-Chemical cells, galvanic cells, chemical and electrical energy, thermodynamics of electro-chemical cells, standard electrode epotentials, sign convention of electrode potentials, application of Gibbs- Helmhoitz equation to galvanic cells. Concetration Cells.
(Assessment: The student should be evaluated based on the assignments aand objective tests. The student’s analytical abilities (with special focus on academically weak students) should be tested periodically in classes by giving problems). Emphasis should be given by conducting tutorial classes at the end of each unit.)
