Materials Science and Engineering 342
Microstructure and Characterization of Materials
Catalog Data:
Important features of microstructures, including dislocations, surfaces, grain boundaries and interfaces, and techniques for characterizing and quantifying microstructure. Wi Qtr. Three 48 minute lectures per week. Required.
Prerequisites:
MSE 341 and 282 (concurrent), or permissionof the instructor.
Time Distribution:
48 minute lectures on Monday, Wednesday and Friday.
Objectives:
Develop an understanding of the important microstructural features in single-phase and multi-phase materials, and working knowledge of important techniques for structural and chemical characterization of materials, especially those needed for determining microstructure morphology, volume fractions and phase composition.
ABET Criteria 3(a), 3(b), (e) and (k).

Topics/Content:
This is a lecture course designed to follow MSE 341 and complement the MSE 282 laboratory. Whereas the emphasis in MSE 341 was on atomic level structure, MSE 342 will focus on microstructure (dislocations, surfaces, boundaries and interfaces, multiphase microstructures) and characterization of microstructure (optical microscopy and SEM, EDS, XRD).
Topics:
1. Brief coverage of XRD topics (e.g., powder method) needed for lab (2lectures)
2. Basics of optical microscopy and SEM imaging, including instruments, signals,
uncertainties, imaging (SE, BSE), diffraction, resolution, aberrations, depth of field (2 weeks)
3. Composition analysis using EDS, capabilities & limitations (1lecture)
4. Stereology and quantitative image analysis (1 week)
5. Dislocation structure: basic geometries and movement, formation of substructures, detection and measurement of dislocation density (include review of Miller indices) (2 weeks)
6. Single-phase and multi-phase microstructures: structure of surfaces and grain boundaries; measurement of distribution of grain size and shape using optical and SEM data; surface analysis; properties of interphase boundaries; measurement of volume fractions and the distributions of size, shape and connectivity of constituent phases (2 weeks)
7. Anisotropy, and measurement of texture using electron back-scattered channeling diffracton (EBSD) and simple explanation based on Bragg (1 week)
Grading Plan:
33% for each of two midterms, and 33% for the final exam (non-comprehensive)
Professional Component Content:
Engineering Science: 1 credit or 100%
Design Component Content:
In the lectures in MSE 342 (concurrent), students learn the associated principles associated with the design and operation of major instruments and techniques for structural and chemical characterization of materials. In the labs they integrate these principles with their own hands-on experience with an X-ray difrractometer, search/match software, SEM/EDS, OM and quantitative image analysis.
Relation to Program Objectives:
1. This course applies basic science and engineering concepts to develop a fundamental understanding of defects and microstructural features in materials (Program Objectives #1 and 2).
2. Students are presented with the basic operation and capabilities of the principal characterization methods used in materials science, namely XRD, optical microscopy, SEM and TEM (Program Objective #2).
3. This course provides the basis for understanding how microstructure and crystalline defects control the properties of materials, and how these features can be characterized – concepts that are fundamental for graduate research and employment in the area of materials design (Program Objective #4).
Academic Integrity, Academic Misconduct
Academic misconduct may be found in any action that tends to distort the accurate assessment of any student’s individual accomplishments that are evaluated for the purpose of grading or conferring academic credit. Note that a student may be guilty of academic misconduct, for example, by cheating, collaborating, plagiarizing, or by allowing another student to cheat, collaborate, or plagiarize. Note also that the distortion applies, for example, to exams, homework assignments, and laboratory work. To the extent that any class activity (for example: attendance or participation) is used for evaluation for the purpose of grading or conferring academic credit, falsifying or distorting such activity, or permitting another student to falsify or distort such activity, represents academic misconduct.
Additional guidance about what represents academic integrity and misconduct, and related university-wide policies and procedures are available at the following locations:

Course-specific exceptions or amplifications to the departmental and university statements outlined above will be provided by the faculty instructor in writing, preferably as part of the course syllabus.
Note: Students should not request nor accept guidance on these matters from a teaching assistant, fellow student, or anyone other than the faculty instructor of record for this course.
Disabilities Statement
Any student who feels s/he may need an accommodation based on the impact of a disability should contact the Office for Disability Services at 614-292-3307 in room 150 Pomerene Hall to coordinate reasonable accommodations for students with documented disabilities.
