Relationship to Student Outcomes
This course relates to Student Outcomes: EAC b, EAC c, EAC d, EAC e, EAC i, EAC k.
Course Learning Outcomes. Students will:

1. Develop an ability to use the techniques, skills, and modern tools necessary to perform x-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy and related microanalytical techniques. (EAC k)

2. Acquire an ability to conduct experiments, analyze and interpret data, and to relate the composition and atomic, structural and microstructural configuration with other material properties. (EAC b)

3. Acquire an ability to prepare various types of specimens for microstructural research and microchemical analysis. (EAC c)

4. Develop an ability to function on multi-disciplinary teams. (EAC d)

5. An ability to experimentally determine the crystallography of simple structures and relate this structure to relevant Miller indices, reciprocal space, structure factors, stereographic projections, pole figures and inverse pole figures. (EAC e)

6. Develop an understanding that materials characterization instruments are continually being developed and improved, requiring continuing education to learn about advances in examining key material microstructures. (EAC i)

Prerequisites by Topic

All topics require ENGR54 as a prerequisite.

Lecture Topics:
  • Review of the crystallography of simple structures, Miller indices, the stereographic projection, pole figures, and inverse pole figures.
  • Review of diffraction theory, x-ray diffraction (XRD), reciprocal space and the structure factor relevant to laboratory exercises.
  • X-ray generation, the x-ray diffractometer and modes of operation relevant to laboratory exercises. Specimen preparation for XRD.
  • A high level introduction to the scanning electron microscope instrument and its imaging modes.
  • Specimen preparation relevant to laboratory exercises.
  • Imaging modes on the SEM, and signals available for image generation (SE, BSE, EDS).
  • The instrument in detail (electron guns, electron optics, vacuum requirements, specimen stages, detectors, scanning systems and displays, image recording systems).
  • Image capture, digital image processing, and image archiving.
  • Experimental techniques of energy dispersive x-ray spectroscopy (EDS).
  • Strategies for SEM imaging and choosing operating parameters (accelerating voltage, beam current, apertures, working distance, etc.) to maximize information content of data recorded.
Class Schedule:

Meets for 3 hours of laboratory each week for 10 weeks.

Computer Usage:

Computer literacy and basic skills are required for performing analysis using software.

Laboratory Projects:

3 hours per week, exercises designed to (1) examine and develop expertise with primary SEM imaging and microanalysis modes, and (2) explore x-ray diffraction techniques and carry out identification of unknowns by powder x-ray diffraction approaches.
