Overview

This specialization extends upon the initial introduction specialization, and like the other specialization, it introduces a limited number of new materials science and engineering concepts. Presentations are at the concept level without being marred in heavy mathematics. Topics in this specialization topic include strengthening of metal, polymers, ceramic materials, and composite. Some of the position titles that may benefit from this course include Materials Engineer, Chemical Engineer, Electrical Engineer, Aerospace Engineer, Materials Quality Control. Others who are want to explore the world of materials will find it helpful.

This course will introduce the major types of ceramics and their applications. We will learn about the different methods used for glass strengthening; the factors that determine a ceramic’s crystal structure; the key characteristics of composite materials; and the different structures of fiber-reinforced composite materials. We will discuss reasons for creating various types of composites.

This course will introduce age hardening and how to use a phase diagram to identify an alloy that is eligible for age hardening. The key factors that affect nucleation and crystal growth will be investigated. In addition, an introduction to polymer science will be given. The key differences between thermoplastic and thermosetting polymers will be introduced. Strengthening mechanisms will be introduced. We explore what happens to the properties of a polymer as you increase or decrease the extent of cross-linking. major polymer synthesis methods will be shown. We will review polymer selection for various applications. In addition, how structural properties vary with temperature will be presented. We explore the significance of the glass transition temperature of a polymer to its thermal and mechanical properties.

In this course, we will explore the electrical properties of materials and classify different materials as conductors, semiconductors or insulators. We will look at some examples of conductors, semiconductors and insulators, and note the key factors that cause the differences in their electrical properties. We will use rudimentary band theory to show how temperature impacts the conductivity of the three classifications of materials. We will learn what causes the differences in electrical behavior of a p-type versus an n-type semiconductor in a p-n diode.
