Specific Goals for the Course

1. All Students

A. Recognize basic MSE nomenclature, basic microstructure, associate terms with the appropriate structure/phenomena, and be able to differentiate between related structures/phenomena. Examples:

  • FCC and BCC crystal structures.
  • Ionic and Covalent crystal structures.
  • Elastic and Plastic deformation.
  • Isomorphous and eutectic phase diagrams.
  • Interstitial and vacancy diffusion mechanisms.
  • Polymers exhibit a distribution of molecular weights.
  • Identifying and drawing crystallographic planes and directions.

B. Perform simple calculations to quantify material properties and microstructural characteristics. Examples:

  • Interplanar spacing of a family of atomic planes given a x-ray diffraction pattern.
  • Equilibrium vacancy concentration at a given temperature.
  • Dimensional changes associated with elastic and plastic deformation.
  • Fracture strength for a given flaw size.
  • Phase composition and fraction using phase diagrams.
  • Apply Reuss and Voight models to determine modulus of composites.

C. Recognize the effect of composition and microstructure on material properties. Examples:

  • Hall-Petch effect
  • Dislocation density effect on yield strength and electrical conductivity.
  • Alloying effect on yield strength and electrical conductivity.
  • Inverse relationship between yield strength and fracture toughness.
  • Correlation between type of atomic bonding and the mechanical and electrical properties of different classes of materials.

2. Most Students

A. Take information from a known situation and apply it to a new situation. Examples:

  • Effect of temperature and applied stress on the peak positions in a XRD pattern.
  • Simple calculations with multiple steps.

B. Predict property response or microstructural changes based on imposed conditions. Examples:

  • Predicting microstructure using a phase diagram.
  • Predicting microstructure using a TTT diagram.
  • Effects of temperature and alloying on the resistivity of metals.

C. Assess the interplay of two material properties. Examples:

  • Effect of atomic bond strength on Young’s modulus, coefficient of thermal expansion and melting temperature.
  • Determine if a material will yield or rupture at a given applied stress.

3. Some Students

A. Ability to explain the fundamental basis for materials phenomena. Examples:

  • Role of electron scattering in alloying and temperature dependence of the resistivity of metals.
  • Role of dislocation multiplication in strain hardening.

B. Describe a processing sequence to produce materials with specific microstructure and/or properties.

C. Assess the effect of anisotropy on material properties.
