Seeing is believing, characterization and analysis are essential components for researches in many areas.
Investigation of microstructure by using electron microscopy is one of the most important and challenging part for
characterization. As the advances of materials science, nano-tech, thin films, and precision machining, lots of
attentions have been drawn to the observation and manipulation of microstructure. For instance, the manipulation of
point defects can modify the properties of two-dimensional materials, the mechanical properties of materials are
controlled by the distribution and evolution of dislocations, the modification of interfaces structure can change the
property of films and increase the product quality of additive manufactured materials, grain boundary engineering
has been used to strengthen metals, deposition of films can increase the resistance to fracture, corrosion and
irradiation. The ability for characterization and analysis of microstructure is critical for students planned to work in
area of design of structural materials, thin films, semiconductor, micro- and nano- devices, precision machining, and
additive manufacturing.
The objective of this course is to acquaint both undergraduate and graduate students in Mechanical Engineering,
Materials Science and Engineering, Applied Physics, Chemistry, Aerospace Engineering, and Microelectronics
Science and Engineering with fundamental theory, application and analysis methods of microstructure, and enhance
the student’s ability of understanding and using the theory of microstructure formation and evolution to solve
engineering problem. By acquainting student with the basic theory and characterization methods in scanning
electron microscopy, focused ion beam, transmission electron microscopy, and electron back-scattering diffraction
pattern analysis, improve their understanding of microstructure in different scales, and promote their researching and
working ability in the related field.
