Unformatted text preview: 1 ENGR 220 Fundamentals of Materials ( Disclaimer: All content, dates, times, etc. subject to change, as dictated by prevailing circumstances. ) Fall 2011 (AY 2011-12) Dr. Richard Knight E-mail: knightr@coe.drexel.edu Phone: 215-895-1844 Office: LeBow 335 1. Purpose and Rationale In almost every case, the development and use of engineering technology today requires a consideration of materials. It is common for engineering breakthroughs to follow closely on the heels of the development of a new or improved material. Many potentially significant engineering designs lie dormant awaiting improved materials. Many engineering developments also reach a catastrophic end due to misuse of the available materials of construction. Contemporary engineers therefore need a basic understanding of materials in order to be able to capitalize on the development of new materials and to utilize the materials that are currently available effectively. Materials are endemic to all branches of engineering and without materials engineers cannot function. Everything that is made utilizes materials in some form or another and this mandates informed design with, and selection of, materials on the part of the engineer. Materials thus represent a common denominator spanning across all engineering disciplines and a broad-based treatment of the fundamentals of materials is essential for all engineering students. 2. Course Objectives The key to understanding the nature and behavior of materials is recognition of the fact that material properties, and thus their performance, are a function of both composition and structure. The composition (chemical) variable is usually obvious; the structure variable can often be obscure since it includes the effects of electron configurations, atomic arrangements and defects at the atomic level. Furthermore, processing, or synthesis, controls the structure of a material. For a given composition of material, different processing routes can give rise to different structures, and hence to different properties. The general objective of the course is to provide a clear understanding of processing, microstructure and properties. Specific course objectives are to: Recognize and discriminate between the various classes of engineering solids (metals, ceramics, polymers, etc.). Understand solids at the atomic level in terms of inter-atomic bonding and energy. Establish a quantitative picture of the structures of crystalline and non-crystalline (amorphous) solids. Explain atomic movements in solids in terms of diffusion mechanisms and the mathematical laws of diffusion. Quantitatively characterize the electrical behavior of conductors, insulators and semiconductors in terms of the number and mobility of charge carriers....
