MATERIALS SCIENCE and ENGINEERING ME 202,

Atomic bonding in solids, bonding forces and energies, primary and secondary bonds. The structure of crystalline solids, lattice, unit cell, and crystal systems, density computation, crystal directions and planes, linear and planar atomic densities. Impurities and imperfections in solids: point, line and interfacial defects.

Atomic vibration and diffusion. Mechanical properties of materials. Elastic and plastic deformation and recrystallization.

Phase diagrams of single phase & multiphase materials with emphasis on iron-iron carbide system (steel & cast iron). Thermal processing of metals & alloys: annealing, normalizing, quenching and tempering, composite materials, polymers. Impact, fracture, fatigue and creep properties and introduction to fracture mechanics.

This course is to demonstrate knowledge of the basic concepts of structure and properties of materials, to apply this knowledge efficiently, and independently to analyze the structure and properties of different materials used in real engineering applications. Unit 1: Introduction to MaterialsHistorical perspective, materials science and engineering, classification of materials, advanced materials, processing/structure/properties correlations. Unit 2: Atomic Structure and Interatomic BondingAtomic structure fundamentals, electrons in atoms, the periodic table, bonding forces and energies, primary interatomic bonds, secondary bonding, materials of importance, molecules.
