To understand the different classes of materials, and have a fundamental idea about the crystal structure.

To provide a basic understanding of materials engineering comprising of the extraction, processing, microstructure, and mechanical properties of the materials.

To learn about the thermodynamic principles responsible for the metal extraction process and also explore the different types of extraction process.

To analyze the mechanical and fracture behavior of materials and understand the effect of microstructures such as phases, defects etc. and various strengthening mechanism on the overall structure-property relationship. Apart from the mechanical properties, the unersatnding associated with the electrochemical and corrosion behavior of metals and alloys are needed to be understood.

1. Upon successful completion, students will be able to gather knowledge about different classes of materials and explore their atomic structure including the crystal structure, unit cells and crystallographic orientation.
2. The course will not only provide an understanding of the thermodynamic concepts for the metal extraction process, but also be able to describe the principles and steps involved in various metal extraction processes.
3. The course will provide insights into the mechanical and fracture behavior of materials and also decipher the underlying mechanics responsible for failure.
4. The course addresses the role of defects (points, line, interfacial, volume) and various strengthening mechanism in materials, helping student in understanding their impact on mechanical properties.
5. The students will realize the importance of phases and phase transformation in metal and alloys.
6. This course also delves into the understanding of various characterization techniques, specifically Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) etc. to examine material structures.
