MatE271 Introduction to Materials Science and Engineering
Syllabus
Introduction to the structure and properties of materials relevant to practicing engineers
(i.e., primarily metals, polymers and composites). Crystal structure and imperfection in
metals. Diffusion mechanical properties and failure mechanisms. Phase equilibrium
diagrams and heat treatment principles for steels, cast irons, and aluminum alloys.
Material selection and engineering applications.

Course Objectives and desired Learning Outcomes:
1. Predict approximate physical and mechanical behavior of a material based on the
type of bonding present (covalent, ionic, metallic, and/or van der Waals) and the
presence of any of the several types of defects common in condensed matter.
2. Use knowledge of the crystal structure (BCC, FCC, and HCP) of a metal to make
general predictions about the metal’s ability to plastically deform.
3. Calculate the extent of diffusion-driven composition changes based upon
composition, time, and temperature.
4. Predict the equilibrium microstructure of a material comprised of two constituents
(e.g., Fe and C or Al and Cu) given the binary phase diagram and thermal history
of the material.
5. Use and alloy time-temperature-transformation diagram to specify a suitable heat
treatment to produce any of the possible major microstructures.
6. Specify an appropriate heat treatment to precipitation harden a binary alloy given
the phase diagram for that alloy.
7. Select materials for different applications based on the constraints of the given
applications.
8. Recognize the basic causes of metallic corrosion and recommend methods of
prevention.
