  2. Visual Materials... • Texts • ● Fundamentals of Materials Science and Engineering, by William D. Callister, Jr.; John Wiley & Sons, Inc. • References • Engineering Materials 1: An introduction to their properties and applications - M. Ashby & D.Jones • Engineering Materials 2: An introduction to microstructures, processing & design - M. R. Ashby & D. R. H. Jones

  3. IE 251 Manufacturing Materials • Introduction to the structure, processing, properties and performance of Manufacturing materials • metals, polymers, glasses, ceramics and composites • Case studies covering... • selection of materials • component design • analysis of component failures

  4. The course objectives for the student • To develop an understanding of the impact of modern materials on the performance of products that are encountered daily, such as bicycles, beverage containers, and sports equipment. • To develop an understanding of the classes of engineering materials (metal alloys, polymers, ceramics and composites), with an emphasis on their properties and their uses. • To understand how the materials selection process fits into the product design, development and manufacturing process used by industry today. To come to appreciate that product cost and quality play a key role in the materials selection process. • To recognize that environmental regulations (emissions), and societal pressures (energy, safety) can strongly influence the adoption of new technologies and alternate materials. • To discuss the competition of alternate materials for the same application

  6. 1. Engineering materials and their propertiesKey points • Enormous range of engineering materials • Types of material properties • Range of properties within and among materials classes • Development of new materials and their impact on design • Failure to select suitable materials can lead to failure of engineering structures and systems • Some failures can be quite spectacular • Liberty ships • Comet (1st commercial jetliner) • Space Shuttle Challenger

  7. There are more than 50,000 commercially available materials with which an engineer may choose to design Table 1.2 • Metals and alloys • Steel, aluminum, etc. • Polymers • Polyethylene, polystyrene, nylon, epoxies, etc. • Ceramics and glasses • Alumina, silica, silicon carbide, etc. • Composite materials • Fiberglass, carbon fiber reinforced polymers, etc. • Natural materials • Wood, leather, silk, bone How to Choose?
