MS3001 Materials Science and Engineering I

This is the first course of an introductory two-course sequence of the MAE Materials track. This course will introduce standard emphasize the basic principles of processing-structure-property relationships in materials and relate this to engineering materials of naval relevance. Regarding processing-structure-property relationships, standard characterization techniques will be introduced. Additional topics will include the following: imperfections in solids, diffusion, mechanical properties, strengthening mechanisms, and phase diagrams. The course will introduce welding and brazing and material transformation fundamentals related to metal joining.

Course Learning Outcomes

  • Identify, compare, and describe three-dimensional packing of atoms for different types of materials. Recognize the concept unit cell and Bravais lattices, differentiate crystal structures, and examine basic X-ray diffraction patterns. Justify knowledge on crystallography and propose materials for specific applications.
  • Be able to identify common metallic microstructures.
  • Identify types of defects and recognize effects in materials properties.
  • Understand fundamental laws of diffusion. Identify and contrast diffusion mechanisms and estimate values for concentration or time in diffusion problems. Examine factors that influence diffusion.
  • Learn basic principles of stress and strain, and related mechanical properties of materials. Given an engineering stress-strain diagram determine modulus of elasticity, yield strength, tensile strength and estimate percentage of elongation.
  • Compute ductility in terms of elongation and area reduction for material loaded in tension to fracture. Identify and compare hardness testing techniques.
  • Understand slip systems and their implication in plastic deformation.
  • Describe and differentiate strengthening mechanisms and heat treatment of metals.
  • Explain and perform computations related to phase transformation including lever rule, interpretation, and construction of phase diagrams. Revise Iron-carbon phase diagram and identify microstructural implications.
  • Understand fundamental concepts of welding microstructures and possible defects.
