from 9:45 to 11:45 a.m.

Rm: Carver 001

Audience

This course should be of interest to engineering students who are interested in an overview of underlying physical mechanisms that control the macroscopic behavior of common classes of engineering materials. The course is a 3. Cr. with a prerequisite of  Chem 167 or 177.

Course Objectives
The objective of this course is to introduce students to different aspects of bonding, structure and properties of solids. Relationship between the structure and defects in solids and their mechanical, thermal, electrical and optical properties. General overview of properties and processing of metals, ceramics, polymers and composite material systems with an emphasis on control of mechanical properties of steels and lightweight load-bearing metals. Case study of lightweight structures. 

Anticipated general outcome:

1. Physical understanding of material behaviors

2. Ability to optimize material selection and properties to satisfy single or multifunctional engineering           applications. 

Specific  objectives:

  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.
