Phase Transformation in Materials

Phase Transformation in Materials. Instructor: Dr. Krishanu Biswas, Department of Materials Science and Engineering, IIT Kanpur. This course will deal with the basics of phase transformation in materials. Using thermodynamics, kinetics of phase transformation, different liquid to solid and solid to solid transformations will be covered in this course. (from nptel.ac.in)
