# MT 202: Metallurgical Thermodynamics

## Introduction to the Course

This three credit course (3:0) is offered in the fall semester.
The Course ID is MT 202. It is a core course for the students in the ME
program. It is also open to research students enrolled in the M.Sc.(Engg.)
and Ph.D. programs.

We will start with the laws of thermodynamics;
we will then use some nice mathematical ideas and formalisms, which take
the two "Great Laws" further to their
logical consequences. We will apply the laws (and their consequences)
to problems and phenomena in materials science. Along the way, we will also
study the fundamentals of statistical thermodynamics, which explain
how interactions among atoms and molecules at the microscopic level
can be averaged to arrive at the same conclusions as those of
classical (macroscopic) thermodynamics.

We will study many different things, including:
specific heat of solids, interstitial and substitutional solid solutions,
solution models, phase diagrams, stability criteria, critical phenomena,
ordered alloys, defects, ternary alloys and phase diagrams, surfaces and
interfaces. Finally, we will also cover property tensors, and how
crystalline anisotropy can be described by them.

Thermodynamics, being an absolutely fundamental subject, is important to all
of science. Therefore, you will find many ways of teaching the subject,
with a different emphasis in different fields of science. But the number of
"thermodynamic principles" is very small, and they are universally valid.
In other words, the starting point - the fundamental laws - taught in all
the fields are the same, but they are applied to different problems in
different fields. While the diversity of texts (listed on
this page),
each with its own notation
and peculiar collection of problems, may appear to be a pain for a starting
student, the real benefits come a little later: once the basics are
mastered, learning new things in a new field becomes easier if we approach it
from the thermodynamic angle; the learning curve is now far less steep.
