Clayton First semester 2008 (Day)

Synopsis

This unit deals with structural and chemical changes (phase transformations) at the atomic scale and impacts of such changes on the performance of materials in structural applications. The major strengthening mechanisms involving interactions of dislocations with obstacles are discussed This unit examines the factors that are important in influencing the structural and chemical changes and the principles for microstructrual design. It demonstrates how to use the design principles to manipulate, in a controlled manner, the alloying additions and thermomechanical processing to tailor the properties and thus the performance of materials.

Objectives

To develop:

1. a thorough understanding of the characteristics and mechanisms of solid-state phase transformations in and their impacts on the performance of engineering alloys

2. an understanding of the role of dislocations in determining the mechanical properties of metals and alloys

3. in depth understanding of strengthening mechanisms in metals and alloys

4. a knowledge of basic principles of microstructural design.
