Thermodynamics and Kinetics of Materials

By Prof. Saswata Bhattacharya   |   IIT Hyderabad
Learners enrolled: 91
This course introduces the fundamental concepts of thermodynamics and kinetics to students of Metallurgy and Materials Engineering. Major topics covered by this course are laws of thermodynamics, thermodynamic potentials, principles of phase equilibria, theory of solutions, thermodynamics of chemical reactions, thermodynamics of surfaces, rates of reactions, principles of irreversible thermodynamics, phenomenology of diffusion and atomic mechanisms of diffusion in solids. At the end of this course, a student learns how to apply thermodynamic principles to assess the feasibility of processes, calculate phase equilibrium conditions in multicomponent, multiphase materials, construct phase diagrams, calculate thermodynamic driving force for phase change, understand the principles of kinetics of irreversible processes such as rates of reactions and diffusion processes in materials. The course also includes a virtual laboratory where the student learns to compute phase equilibria and phase diagrams of unary, binary, and ternary systems and perform simulations of diffusion using the free ThermoCalc education package and open source Pycalphad and FiPy.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 30 April 2023 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.


Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Hyderabad. It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
