Elements of Materials Science and Engineering

MESc 5025, Index 7239 (4 credits)

1996 Fall Semester; 3:00 -4:50 p.m. M., W.; Williams 210

Instructor: H. Marand

This two-semester sequence of courses is intended as an overview of concepts used in generic materials research and development. The objective is to provide the students with the tools necessary to gain an understanding of structure, composition and properties of a material and, to a lesser extent, of the relationships among these parameters. The first semester covers scientific principles relevant to the structure of materials; the second semester emphasizes common types of material properties.

1. Introduction (Fall)

Structure, composition, processing and properties of materials and their interrelationships

2. Structure and Composition (Fall)

(a) Thermodynamics

First, Second and Third Laws; Thermodynamic Equations; Solutions; Chemical Reactions

(b) Bonding in Solids

From the Atom to the Molecule or Ion to the Solid

(c) Structure of Crystalline Materials

Lattice; Symmetry; Structure; Structural Characterization; Imperfections in Solids

(d) Non-Crystalline Solids

Structure; Formation (Glass Transition vs. Crystallization)

(e) Fluid Dynamics

Mass, Momentum and Energy Transfer; Newtonian vs Non-Newtonian;

Laminar vs. Turbulent

(f) Heat Transfer

Thermal Conductivity; Heat Transfer with Conduction and with Convection

(g) Diffusion

Ficks law; Continuity Equation; Diffusion in Solids

3. Material Properties (Spring)

(a) Mechanical

Stress; Strain; Elastic Deformation;Yielding; Time Dependent Deformation; Fracture;

Fatigue Testing

(b) Thermal

Heat Capacity; Thermal Expansion; Thermal Conductivity; Thermal Stress; Thermal

Shock

(c) Electrical

Metallic Conductivity; Semiconductivity; Ionic Conductivity; Superconductivity

(d) Dielectric

Dielectric Dispersion; Dielectric Loss and Strength; Ferroelectricity and Piezoelectricity

(e) Optical

Refraction; Reflection; Transmission and Absorption Factors; Color; Luminescence;

Photoconductivity

(f) Magnetic

Diamagnetism; Paramagnetism; Ferromagnetism;Anti-ferromagnetism; Ferrimagnetism

Text: Books Placed on reserve in the Newman Library. These should also be considered a reading list to prepare the students for the MESc Qualifying Examination.

Grading: The course grade will be determined from seven equally weighted examinations. Examinations will focus successively on : Thermodynamics, Bonding, Structure, Amorphous Solids, Fluid Flow, Heat Transfer and Diffusion.

Any student with special needs or circumstances should feel free to meet with the instructor to discuss accomodations.
