Catalog Description, Prerequisites and Schedule:

Introduction to the materials science and engineering of ceramics, electronic materials, metals and polymers. Bonding; crystallography; imperfections; processing and properties of semiconductors, polymers, metals, ceramics and composites; and phase diagrams. Case studies and demonstrations will be used to exemplify the lecture material. Prerequisite: Physics 112, 114 (concurrent), and Math 242. 3 hours (students may not receive credit for MatSE 200 and TAM 224 (CE 210) or ME 231). 3 hours lecture-discussion/week

Course Topics:

1. Atomic Structure
2. Atomic bonding in solids
3. Metallic, Ceramic, and Polymer Structures: ionic and metallic crystal structures, polymer structures (crystalline, non-crystalline, etc.), Miller indices, diffraction.
4. Defects in solids: vacancies, Frenkel and Schottky defects in ionic systems, dislocations.
5. Diffusion: vacancy and atomic diffusion in solids (time-dependent and time-independent)
6. Mechanical Behavior of Metals, Ceramics and Polymers
7. Deformation mechanisms - metals (dislocation motion, slip, plasticity)
8. Strengthening/Hardening mechanisms (metals, ceramics, polymers)
9. Phase diagrams (phases, phase composition, composition, and microstructure)
10. Kinetics of phase diagrams (brief)
11. Fracture, crack propagation, and simple failure mechanisms (ductile-to-brittle transitions, leak-before-fail criterion, etc.)
12. Composites (isoload and isostrain cases, laminates)
13. Simplified materials selection for design, with examples (e.g., use of Ashby plots, design of leak-before-fail vessels, strong but light, low-deflection/no-fail, cost optimization, etc.).

Course Objectives:

1. To recall chemical bonding, types of bonds, and arrangement of periodic table.
2. To understand the correlation between bonding and structure, and bonding and properties.
3. To introduce concept of crystal structure, and the myriad of structures possible in metals and ceramics, as well as crystalline polymers, including crystal planes and diffraction.
4. To introduce the physical origin of and demonstrate the correlation between structure and properties of materials.
5. To introduce common crystal defects and to understand their role in materials behavior.
6. To provide overview of mechanical behavior of ceramics, metals, and polymers, including concepts of stress-strain curves, elastic response and Poission effect, yielding, necking, fracture, slip via dislocations, ductility, brittleness, strengthening mechanisms, transformation toughening, cross-linking polymers, polymer confirmations. To know how to estimate the effects of the physical effects on mechanical behavior.
7. To introduce students to the concept of phases and phase diagrams, including T-c behavior leads to different microstructures and, hence, varying mechanical behavior due to heat treatment. To understand effects of composition on structural and mechanical behavior, as well as how process history effects materials properties.
8. To introduce and utilize simple concepts of crack propagation, fast-fracture, and failure. To provide failure examples and motivate importance of materials properties in design (e.g., importance fracture toughness, KIc,).
9. To introduce mechanical response of composite materials and to use this information in simple examples of design and failure.
10. To use simplified materials selection concepts for design purposes.
11. To give student broad introductory knowledge of how materials properties ultimately affect engineering design in their respective disciplines, and how such properties lead to limitations.

Course Outcomes:

1. Given type of material (ceramic, metal, polymer), identify type of bonding present, types of crystal structure expected, and expected mechanical responses.
2. Be able to predict expected ordered structures in specific ionic solids.
3. Utilize information about elastic and plastic deformation to predict loads or strains that lead to yielding, necking, or fracture. Identify generic differences between stress-strain response in ceramics, metals, crystalline and non-crystalline polymers, and tissue.
4. Identify common defects in a material, when they are to be expected, and know how they affect material's mechanical properties.
5. Know types of dislocation, how they move, what strain-fields occur and how dislocations interact, what effects are created in crystals when they move, and how they lead to plastic deformation.
6. Understand and identify the stress-strain response of ceramics, metals, and polymers, and know generally how these are altered by strengthening/hardening mechanisms, alloying, etc.
7. Be able to identify phases (and their abundance), eutectics, eutectoid, and peritectic reactions in T-c diagrams, as well as identify simple microstructures that can occur (including possible effects on mechanical response).
8. Utilize concepts of crack propagation and fast-fracture and ductile-to-brittle effects to predict failure of brittle solids, and experience these in simple measurement of design problem.
9. Utilize material index parameters to select materials appropriate to simple design problems, including yielding and fast-fracture.

Assessment Tools:

1. Homework problems involving application of each topic.
2. Three written examinations (one in-class and two more extended take-home) Exams are designed to test the student's understanding of concepts and their ability to apply his/her knowledge.
