A Collaborative Program of the Faculty of Arts & Science and the Faculty of Applied Science and Engineering
Materials science is the study of the structure, properties and applications of all types of materials including metals, ceramics, glasses and polymers. Currently many exciting scientific developments are in the materials field. Notable advances have been made recently in studies of amorphous metals, the quasicrystalline state, liquid crystals, semiconductors, high critical temperature superconductors, biomaterials, high strength polymers, materials processing techniques such as ion implantation and laser melting, and in new categories of engineered materials such as advanced industrial ceramics or composite materials.
Materials science is interdisciplinary, drawing on the basic sciences of chemistry and physics and on more applied subjects such as metallurgy, ceramics and polymer science. Its tools and techniques include electron microscopy, x-ray diffraction, surface analysis using Auger emission spectroscopy, x-ray photoelectron spectroscopy, etc.
Introductory Materials Science, MMS 150H, is designed to appeal to a wide variety of student interests. Other materials science courses are available to students having the prescribed prerequisites and the approval of the Undergraduate Student Counsellor. The specialist program in Materials Science is coordinated jointly by the Departments of Chemistry and Metallurgy and Materials Science. For further information on the program, consult the coordinators listed in the Materials Science Program section below. For further information on materials courses from the Faculty of Applied Science and Engineering, consult the Undergraduate Student Counsellor.
Undergraduate Counsellor: Professor W.A. Miller, Department of Metallurgy and Materials Science, Wallberg Building, Room 140E (978-1472)
MATERIALS SCIENCE (Hon.B.Sc.)Consult Undergraduate Associate Chair, Department of Chemistry and Professor W.A. Miller, Department of Metallurgy and Materials Science.
Enrolment in this program requires completion of three courses; no minimum GPA required. Specialist program: S24241 (13 full courses or their equivalent, including at least one 400-series course)
NOTE: The program consists of a core curriculum and electives. By suitably choosing electives, students follow one of two streams: 1.) Materials Chemistry, or 2.) Materials Science and Engineering. See Notes 1, 2 and 3 below.
First or Second Year: MMS 150H (see Notes 1 and 2)
2. Materials Science and Engineering Stream:
For Distribution Requirement purposes, all MMS and CHE courses are classified as Science courses.
1. The MMS and CHE courses below are administered by the Faculty of Applied Science and Engineering, and are subject to the rules and regulations of that Faculty, including those for term dates and examination periods. The examination in MMS 150H is scheduled at a time common to the examination periods of the Faculty of Arts and Science and of Applied Science and Engineering.
Introduction to the fundamental relationships between the structure and properties of materials. Quantitative treatment of physical phenomena pertaining to structure, phase equilibria and the mechanical, physical and chemical properties of materials.
The theoretical and experimental interpretation of the structure of various inorganic materials. Crystalline and amorphous materials in terms of electronic structure of atoms, atomic bonding, atomic coordination and packing. An introduction to defects in crystals. Experimental techniques include: optical and electron microscopy, x-ray diffraction, Auger electron spectroscopy, x-ray photoelectron spectroscopy and secondary-ion mass spectrometry.
Introduction to existing and future challenges in the field of materials engineering. The course is given by a number of staff members who use several examples to illustrate materials challenges in the production, performance, manufacturing and design of all classes of materials including metals, ceramics, polymers and composites.
Thermodynamics of material-electrolyte systems, Nernst equation and Pourbaix diagrams, and rate theory through activation and concentration polarization. Corrosion of metallic, polymeric, ceramic, composite, electronic and bio-materials, and mechano-chemical effects of stress corrosion, hydrogen embrittlement and corrosion fatigue. Corrosion prevention in design and the use of expert systems in materials selection.
The mechanical behaviour of engineering materials including metals, alloys, ceramics and polymeric materials. Macro- and micro-structural response of materials to external loads; load-displacement and stress-strain relationships, processes and mechanisms of elastic, visco-elastic, plastic and creep deformation, crystallographic aspects of plastic flow, effect of defects on mechanical behaviour, strain hardening theory, strengthening mechanisms and mechanical testing.
Production of amorphous materials: amorphous metals and silicate-based glasses, techniques for growth of single crystals. Metallic and ceramic powder processing and other forming methods, sintering. Grain growth and microstructural development. Vapour deposition processes.

Phase transformations in binary systems: solidification, precipitation from solid solution, binary invariant reactions. Diffusional transformations, nucleation and growth, diffusionless or martensitic transformations. Second order transformations. Spinodal, massive and order-disorder transformations.
Nature of brittle and ductile fracture, macro-phenomena and micro-mechanisms of failure in various material types, mechanisms of fatigue failure: crack nucleation and propagation, Griffith theory, stress field at crack tips, stress intensity factor and fracture toughness, crack opening displacement, energy principle and the J-integral, fracture mechanics in fatigue, da/dN curves and their significance. Fatigue analysis and fundamentals of non-destructive testing.
Introduction to polymer synthesis, structure, characterization and mechanical properties. Topics include addition and condensation polymerization, network polymerization and crosslinking, molecular mass distribution and characterization, crystalline and amorphous structure, glass transition and crystalline melting, forming and additives for commercial plastics, dependence of mechanical properties on structure, viscoelasticity, yielding and fracture.
Selection and design of engineering materials, allowing the most suitable materials for a given application to be identified from the full range of materials and section shapes available. Case studies to illustrate a novel approach employing materials selection charts which capture the important properties of all engineering materials, allowing rapid computer retrieval of information.
Materials for surgical implants. Influence of mechanical, chemical and physical properties of metals, ceramics and polymers as well as interactions at the implant-tissue interface. Materials for use in orthopaedic, dental and cardiovascular applications.
Material parameters and electronic properties of semiconductors. The material parameters are discussed in terms of the preparation and processing methods and the required electronic properties of engineering devices. Some techniques for evaluating electronic properties are discussed.
Structure-property relationships in metals, ceramics, polymers, with an emphasis on composite materials. Creep, fracture toughness and corrosion of each class of material. Use of special alloys, advanced ceramics and fibre reinforced composites to meet unique performance requirements.
The effect of processing on polymer properties using a case study approach. Properties to be examined include molecular, physical, mechanical and flow behaviour, while processing examples include polymerization of methyl methacrylate, reactive extrusion of polyethylene, blending of polyethylene with polypropylene, micro-encapsulation by spray drying and recycling of waste plastics.
A single term thesis to provide students in the Materials Chemistry stream with some exposure to a research topic in materials science and engineering, normally closely related to the current research of a departmental staff member. The grade is based on an oral presentation, a poster presentation, and a written dissertation.
An experimental research topic in materials science and engineering involving original work normally related closely to the current research of a departmental staff member. The final grade is based on two oral presentations, a progress report on the Fall Term work, a poster presentation and a written dissertation.
