Phase Diagrams in Materials Science and Engineering

Phase Diagrams in Materials Science and Engineering. Instructor: Prof. Krishanu Biswas, Department of Materials Science and Engineering, IIT Kanpur. Phase diagrams are important for materials science and engineering applications encompassing from structural materials to functional materials, including electronic, magnetic applications. The course is intended to make the students and research familiarize with binary and ternary phase diagrams and microstructure of different materials. It is to be noted that microstructure plays a vital role in deciding the properties of the materials. Thus, it is important to connect the phase diagram information for microstructural evolution.
