Course
Details:
The objective of the course is to provide the background necessary to
make
informed decisions and recommendations concerning the suitability of
materials
for engineering applications. This course extends the knowledge
gained in
the introductory course "Materials Science for Engineers". It
explores the way in which materials are used and the way in which
production
and fabrication routes influence their fitness for purpose. It
will draw
extensively from MSEG 302 and familiarity with the content of that
course will
be assumed throughout.
After briefly introducing some aspects of materials selection and
utilization,
the first segment of the course considers some of those properties of
engineering materials which are of major importance for a practicing
mechanical
engineer. We shall also consider what can be done to determine
whether
the materials contain serious defects which threaten their service
lives.
Next, we shall survey the major categories of engineering materials
and, then,
examine some of the processes available to turn these materials into
actual
components. This sequence is adopted to provide a logical basis
for
making informed decisions concerning materials selection and use for
engineering components. The following section covers the
selection
process itself and will make extensive use of materials selection
charts and
other tools. Finally, examples from a variety of sources will be
presented and examined.
Problems will be assigned and handed in for grading as detailed in the
course
schedule below. Problems are due to the T.A. by 4.00 p.m. one
week
later. No partial credit will be given for late submission.
"Extra credit" is not an option. You must take the exams at the
times and dates set.
You are reminded that, although studying with a partner or group is
encouraged
and has many advantages, the University Policy on Academic Honesty and
Dishonesty requires that anything submitted for credit must be
entirely
your own work.
Course
Outline:
(Approximate dates and coverage: subject to
revision.
If this schedule presents conflicts with religious holidays etc., bring
them to
my attention on or before Sept. 18th. In this regard, note also
that the
midterm exams are not given during regular class hours.
The courtesy of a make up examination or quiz will
only be
extended to students with documented evidence of medical or other
serious
problems.)
