Specific Goals for the Course

1. All Students

A. Ability to use direct and indirect approaches for assessing structural and microstructural features and related properties in crystalline and non-crystalline materials. Examples:

  • Know the experimental methods by which data is collected.
  • Presentation of data in laboratory reports.
  • Develop sense of measurement, process and performance variability.

B. Know typical values of material properties. Examples:

  • Young’s modulus of typical polymers, metals and ceramics.
  • Electrical resistivity values for metals versus insulators.
  • Relative fracture toughness values of ceramics, brittle polymers, and ductile metals.

C. Ability to recognize and concisely describe molecular, network and crystal structures, crystallographic terminology and symmetry in different crystalline and non-crystalline materials. Examples:

  • Distinguish between radial distribution functions of amorphous and crystalline material
  • Identification of crystal structures, directions and planes using 3-D ball and stick models
  • Stereographic projections, Euler angles.

D. From raw data or literature values, process information pertaining to atomic scale structure and microstructure, and materials properties. Examples:

  • Lattice parameter and crystal structure of cubic metals from x-ray diffraction patterns.
  • Transform force-displacement data to stress-strain curves.
  • Calculate grain size from a micrograph using line intercept method.
  • Determine resistivity of a metal alloy from resistance measurements.

E. Effective written communication in lab reports.

F. Effective presentation of data in laboratory reports via Tables, Plots and Figures.

2. Most Students

A. Ability to relate specific microstructural features and environmental factors to material properties. Examples:

  • XRD peak shifts associated with solid solution alloying.
  • Density measurements and material composition.
  • Resistivity measurements and atomic bonding characteristics.
  • Yield stress, degree of cold work and dislocation density.

B. Deconvolute competing microstructural phenomena. Examples:

  • Hall-Petch and recrystallization (grain size and dislocation density effects).
  • Effects of temperature and alloying on the electrical conductivity of metallic alloys.

C. Assess validity of experimental data. Examples:

  • Do experimental values make sense relative to expected values?
  • Problems with using data past the yield stress to calculate Young’s modulus.

D. Recognize experimental factors affecting data. Examples:

  • Measuring Young’s modulus with and without an extensometer.
  • XRD on samples where the grain size approaches the sample size.

3. Some Students

A. Without prompting, apply their knowledge to explain materials phenomena in laboratory reports. Example:

  • Solid solution hardening as the difference in yield stress between Cu and brass.

B. Make connections between different physical phenomena. Example:

  • Ductile-brittle transition observed via Charpy testing leading to a discussion of the temperature dependence of yielding and fracture behavior in FCC versus BCC metals.
