Prerequisite: CHEM 105 or consent of Department.]{.mark} ### Course Objectives & General Content At the conclusion of the course, the student shall be able to demonstrate knowledge in tasks dealing with: -Declarative knowledge -- the what: Proper use of relevant vocabulary; definitions; magnitudes of constants -Procedural knowledge -- the how: Correct methods of solving problems -Conditional knowledge -- the when: Application of theory and problem solving methods to different situations -Reflective learning -- the why: Ability to explain how theoretical concepts apply to observations and behavior Assessment will be through written communication, calculations, and application of concepts to common and new situations. Knowledge is defined as having the ability to perform the above tasks to solve relevant problems that agree with expert opinion (i.e., a level of competence). The use of appropriate language and terminology is also necessary. ### Learning Outcomes By the end of this course, students should be able to: 1\. Recall terminologies and magnitudes of constants, fundamental to the field of Materials Science, and demonstrate their knowledge through proper usage. 2\. Describe different types of bonding, classify materials, and relate the mechanical thermal, electronic and chemical properties of materials to their atomic, molecular, and crystal structures. 3\. Relate materials\' elastic-plastic deformation to applied stress, understand the behavior of common defects, and steps to strengthen materials by controlling defects, 4\. Describe various processing of metals, alloys, and choose pertinent processes for desired characteristics, using the concepts of diffusion, microstructure, and phase transformation. 5\. Predict microstructure and properties of materials based on phase diagrams/phase transformations, and design processing of materials, including heat treatment processes, using the knowledge of TTT and CCT curves. 6\. Inspect, analyze, and diagnose corrosion-related problems, and resolve them through recommending proactive and preventive measures. 7\. Describe the basics of polymers and ceramics, and identify the structure-property relation of polymeric and ceramic products in engineering. Be familiar with laboratory methods for measuring mechanical properties, microstructure, heat treatment of steels, and corrosion. ### Textbooks and References E-text will be supplied on-line through e-Class as PDF files at no charge \[a draft of a text that Nychka and Eadie (profs in CME) wrote for the course\].
