Goals, Topics, and Objectives

Core Course Topics
  1. Introduction to science of materials
    • Describe the concept of process-structure-property relationships.
    • List the major classifications of materials.
  2. Atomic structure and interatomic bonding
    • Describe the different types of atomic structures.
    • Categorize bonds as ionic, covalent,or metallic.
    • Explain how the atomic structure and type of bond determines the properties of a material.
  3. Structure of Crystalline Solids (metals and ceramics)
    • Describe various basic crystal structures.
    • Explain how the crystal structure affect the densities.
    • Describe crystallographic directions and planes.
  4. Defects and Imperfections
    • Describe different types of defects.
    • Identify imperfections such as dislocations and vacancies in metals.
    • Demonstrate imperfections effect the properties of the material.
  5. Diffusion mechanisms
    • Describe different types of diffusion.
    • List factors that influence diffusion.
  6. Mechanical Properties
    • Apply the modulus of elasticity to graph elastic deformations by incorporating Hooke's Law.
    • Create plots of stress vs. strain diagrams from the measurement of the tensile strength of materials.
    • Describe elastic and plastic deformations.
  7. Dislocations, slip, plastic deformation,and creep
    • Explain how dislocations and slip relate to deformations and creep.
    • Explain recovery, recrystallization and grain growth.
  8. Fracture and fatigue
    • Apply the principles of fracture mechanics to predict materials probability of fatigue and failure.
    • Describe fracture concepts (e.g. ductility, brittleness, microstructures).
  9. . Phase Diagrams and phase transformations
    • Interpret phase diagrams of binary and multiphase alloys.
    • Calculate percentages of alloy material at a specific temperatures.
    • Evaluate the different phases and microstructures of ferrous metals from the phase diagrams.
    • Interpret transformation diagrams as it applies to carbon steel.
  10. Manufacturing processes
    • Be familiar with common manufacturing processes for metals, ceramics, and polymers; their effects on structure; and their impact on sustainability.
  11. Thermal processing of metal alloys
    • Understand how annealing, normalizing, quenching and precipitation hardening effect the hardness of materials.
  12. Polymer Structures
    • Understand the mechanisms of polymerization.
  13. Corrosion and degradation of Materials
    • Describe the process of degradation of metals and polymers.
