This course focuses on the chemistry and physics of engineering materials (metals, alloys, and polymers) from a view point
of mechanical engineering. Emphases are put on atomic or molecular interpretation for physical or mechanical properties,
the relationships between physical and chemical properties and performance of engineering materials. Topics to be covered
include atomic structure and bonding in solid materials, crystalline structures, microstructures of the engineering materials,
and an introduction to X-ray diffractometry that enables us to determine the macroscopic properties of the materials such
as tensile strength.
The students will gain fundamental knowledge on materials characterization using X-ray (X-ray diffraction and chemical analyses)
and related crystal structures, and acquire how the microscopic crystal structures strongly affect the macroscopic physical
and mechanical properties of the solid materials.
- The students will be able to understand what X-ray is and how to produce X-ray.
- The students will be able to understand classification of crystal structures that affects physical properties of solid materials.
- The students will be able to understand microscopic mechanism of deformation of solid materials and atomic defects.
- The students will be able to estimate strengths and densities of some simple elements theoretically.
- The student will be able to determine some simple crystal structure by means of X-ray diffraction technique.
