MESc 5025, Index 7239 (4 credits)
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)

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.
