Material science is the science where we study and investigate relationship between the properties of the materials to their atomic structure. Properties are very important in the process of designing the durable components / machines / structures etc. These properties include mechanical properties, thermal properties, electrical properties, optical properties or magnetic properties or deteriorative properties. All of these properties are decided by the atomic arrangement of the materials. Furthermore, a material’s performance will be a function of its properties.

This laboratory provides the know-how of the atomic structures of materials and possible defects therein through various animated computerized models. Properties are also dependent on the micro-structure (grain structure and phase structure) of the materials. With the help of different equipments and machines the students are motivated to analyze the micro-structure and to estimate the resulting properties out of it.
Lab Outcomes

• 1. Conceptually explain the classification schemes that are used to categorize engineering materials.
• Explain the differences in the mechanical behavior of engineering materials based upon bond type, structure, Composition, and processing.
• Describe how and why defects (point, line and interfacial) in materials greatly affect engineering properties and limit their use in service.
• Use binary phase diagrams to predict microstructures and also to understand precipitation hardening.
• Understand how thermal treatments affect the microstructure and, thus, properties of materials.
