MECH 270 Materials Science and Engineering Units: 3.50
This course provides the student with a background in the basic structural concepts of materials and the relationships between processing, structure, properties and performance. The topics will range from atomic bonding and arrangements, through micro-and macro-structures and their influence on properties, to the processing techniques required to produce the desired structures. All current types of engineering materials, including metals, ceramics, polymers, composites and semiconductors are covered.

Course Learning Outcomes:
- Explain and apply the basic mechanisms of (room temperature) elastic and plastic deformation in metals, polymers and ceramics.
- Use phase diagrams to calculate the phases and their quantities present for a given set of conditions, and estimate the microstructures that would be found.
- Explain how diffusion and occurs in a solid, and calculate solute diffusion profiles under both steady state and non-steady state (1 dimensional bar) situations.
- Explain the shape of a time-temperature-transformation diagram, resulting from the competition between nucleation and growth.
- Describe and calculate the effects of the four principal mechanisms of hardening in a metal.
- Explain the effect of changes in temperature on plasticity in metals and polymers; explain the effects of a damaging chemical environment on metals and polymers.
- Define crystallographic planes and directions in cubic and hexagonal symmetry materials, and determine which slip system would activate in a loaded single crystal.
