Indian Institute of Technology Kanpur

Phase Equilibria in Materials (Nature & Properties of Materials-II)

Indian Institute of Technology Kanpur and NPTEL via Swayam

Overview

The course is second part of the broader course on Nature and Properties of materials and would be suitable for undergraduate and postgraduate students of every branch of science and engineering. This course will focus on essentials of thermodynamics, thermodynamic basis of phase diagrams, free energy composition diagrams, phase equilibrium, phase diagrams in unary, binary and ternary systems and correlation of phase diagrams with microstructure evolution. The course will enable a beginner in Materials to understand the phase diagramsINTENDED AUDIENCE:UG students of any branch of engineering and sciences, PG students engaged in materials related researchPREREQUISITES:12th standard, Science BackgroundINDUSTRY SUPPORT:Materials related companies
