Principles and applications of analytical techniques, imaging, diffraction and spectroscopy for materials characterization including crystal structures, texture formation, phase analysis. Nano- and micro-structures of materials including defects and second phases, chemistry, bonding, compositions of materials. Demonstrations and lab experiments involving light scattering and diffraction techniques. Prerequisite: MSE 170; MSE 331. Offered: S.
Class description
This course will cover descriptions of structural characterization techniques, with emphasis on imaging, diffraction, and spectroscopy (as opposed to funtional characterization, such as optical, mechanical, electrical/electronic, thermal, and magnetic, which are covered in other classes that these students take). In imaging, the concepts of image formation, magnification, and resolution, related to light optical and electrron microscopy, and scanned probe microscopies (such as scanning tunneling microscopy and atomic force microscopy). The class will review Braggs law of diffraction and characterization of crystallography using x-ray and electrons, including the review of reciprocal lattice concept, formation and indexing diffraction patterns and phase analysis. In spectroscopy, the basis of atomic structure, chemical versus compositional analysis, and various light, x-ray and electron-based spectroscopy techniques will be discussed with practical examples.
Student learning goals
Students will assess how a material could be structurally characterized and using which tools.
Students will be able to distinguish resolution versus magnification, and the ranges of the values of these parameters, and judge which microscopy is necessary for characterization in a given materials engineering problem.
The students will be able to decide whether surface or bulk microscopy is needed for a given probelm, and what combined set of specific techniques to use.
The students will be able to assess whether a problem requires diffraction, and will know how to do optical, X-ray versus electron diffraction.
Students will have the ability to distinguish between chemical versus compositional spectroscopy, how to do spectroscopic analysis, what fundamental commonalities are among many different spectroscopic techniques, and which ones to use under a given complex engineering situation.
The studenst will know the difference and assess in materials failure situations and in initiating scientific materials research which structural versus functional characterization to pursue (such as in their senior projects other UG or graduate research plans).
General method of instruction
Students will have weekly homework sets, a midterm, and a final, plus a term paper (which requires a report and an oral presentation). There will be a number of demonstration of the characterization equipment, such as scanning and transmission electron microscopes, scanning probe microscopes, nanohardness tester, light optical (e.g., fluorescence) microscopes.
Recommended preparation
Students need to have basic knowledge in introduction to materials science and engineering, physical metallurgy or physical ceramics, thermodynamics or kinetics, mechanical testing failure analysis, and materials selection classes/concepts.
Class assignments and grading
There will be weekly/biweekly home work assignments, for individual work, that will focus on the implementation (with practical engineering and design examples) of the concepts discussed in class; Midterm exam will cover terminology, short concepts questions, and simple technique comparison problems; Final will be similar in structure to MT, but will cover the whole class, plus term paper, which will be an in-depth discussion of one of the techniques, from its fundamentals to practical design and applications with specific materials example(s), both in written and oral presentation formats (so as to prepare students to present their work in both media), and which will help them to prepare in decide on which tool to use in their senior projects which they are expected to decide during this Spring quarter.
Each of the four categories has 25% credit towards the final grade for the class. The HW is for individual work, as is MT; to assess the knowledge level of students in two setting (1 week assigment with all the resources available, versus 1 hr assignment, with closed books and notes); term paper is a tool to prepare student towards doing independent search, research, assessment, discussion, and conclusions on a given scientific topic of theirown choice (so requiring self-disicpline,planning, creativity, and ability to expres onself on paper), plus their ability to present scientific work in written and oral forms; the final is an overall class assessment of the knowledge gained by the student.
