Engineering Materials and Science I

PURPOSE
The purpose of this module is to introduce a novice learner to the most commonly employed engineering materials and provides the learner with the necessary understanding of terminology used to describe engineering materials and their properties as well as the application of these materials. Learners will be exposed to the basic concepts of materials testing methods as well as various aspects of metallic corrosion.

LEARNING OUTCOMES
After completion of this module, learners will be able to:

• describe the properties of various groups of engineering materials;
• demonstrate an understanding of basic crystallography by doing various calculations and describing the solidification process of pure metals;
• demonstrate an understanding of and apply basic concepts of mechanical testing and evaluate the resultant properties obtained;
• understand the basics of the iron-iron carbide diagram and explain the various heat treatments of steel (equilibrium and non-equilibrium);
• demonstrate an understanding of the basic forms of corrosion and be able to apply this knowledge in order to suggest ways to combat corrosion.

CORE CONTENT
Classification of engineering materials, atomic structure of materials, crystal structure and solidification, mechanical properties and deformation of metals, steel and its heat treatment, environmental stability of materials.
