Abstract:
Preparing
a texture suitable for a given
purpose is a central problem
in materials science, which
presents many challenges for
mathematical modeling, simulation,
and analysis. We focus on the
mesoscopic behavior of the grain
boundary system and on understanding
the role of topological reconfigurations
during evolution. We formulate
several types of evolution equations
based on fractional kinetics
and stochastic descriptions,
compare its results with the
simulations and discuss their
limitations and possible extensions
to higher dimensions.

Burak
Ozdoganlar,
Assistant
Professor
in Mechanical
Engineering
and affiliated
faculty in
Materials
Science, receives
$500,000
from NSF's
most prestigious
awards in
support of
the early
career-development
activities.
CAREER:
The Faculty
Early Career
Development
(CAREER)
Program is
a Foundation-wide
activity
that offers
the National
Science Foundation's
most prestigious
awards in
support of
the early
career-development
activities
of those
teacher-scholars
who most
effectively
integrate
research
and education
within the
context of
the mission
of their
organization.
Such activities
should build
a firm foundation
for a lifetime
of integrated
contributions
to research
and education.
NSF encourages
submission
of CAREER
proposals
from junior
faculty members
at all CAREER-eligible
organizations
and especially
encourages
women, members
of underrepresented
minority
groups, and
persons with
disabilities
to apply.
O. Burak Ozdoganlar's CAREER: Mechanics and Dynamics of Micromachining
The demand from many fields, including medical, aerospace, military/defense,
optics, and consumer products, has been driving the need for accurate miniature
parts with complex 3D geometries made from a wide selection of materials.
Mechanical micromachining is seen as one of the most flexible and viable approaches
to manufacture such parts. If successful, this proposal will pave the way for
more effective and economical applications of micromachining, leading to a wide-spread
use of the technique for micro-scale manufacturing in many areas, such as in
the creation of implantable medical devices and miniature, multi-functional consumer
products. In addition, micro-manufacturing will play an important role as a bridge
between the nano and human scales, thereby enabling the utilization of nanotechnology
products in various applications.
This research objective is to develop an understanding of crystallographic effects
on mechanical micromachining of metallic parts, leading to an in-depth understanding
of and associated models for mechanical micromachining of metals in the presence
of the crystallographic effects. Since the amount of material removed is
commensurate with the grain sizes of most engineering metals, the crystallographic
effects play a very significant role in mechanics and dynamics of micromachining.
Without a thorough understanding of these effects, significant advancements in
micromachining science and technology cannot be realized, and commercial
developments of this emerging manufacturing area will be hindered.
Developing an understanding of the crystallographic effects requires an innovative
approach that combines experimental investigations, practical models, and theoretical
models in analyzing mechanics and dynamics of the process and tooling. The
influence of crystallographic effects on the mechanics of micromachining arise
due to plastic anisotropy single crystals, and associated size and orientation
distribution of crystals in poly-crystalline aggregates. The elastic anisotropy
and size distribution of the crystals of tool materials induces considerable
changes to tool dynamic behavior. The experimental part of the research will
be conducted in the Ozdoganlar's Multiscale Manufacturing and Dynamics Laboratory
(MSMDL), which includes a Miniature Machine Tool and unique micro/nano vibration
testing equipment. |

Materials
Science
Research
Science
and
Engineering
Center (MRSEC)
will
receive
$6.5
million
over
the
next
six
years
from
the
National
Science
Foundation
to
continue
creating
new,
super
efficient
materials
for
many
industry
sectors.
"Our
goal
is to
create
new paradigms
for interdisciplinary
work
that
apply
the principles
of basic
science
and engineering
to understanding
the behavior,
development
and application
of various
materials," said Gregory
S. Rohrer,
head
of MRSEC
and Carnegie
Mellon's
Materials
Science & Engineering
Department.
Since
1996,
MRSEC
researchers
have
been
working
to understand
the intricate
nature
of nanoscale
grain
boundaries
in materials.
Most
metallic
and ceramic
materials
used
in aircraft,
automobiles
and computers
are made
up of
many
microscopic
crystals
held
together
by grain
boundaries.
These
materials
are called
polycrystals.
"We
are studying
how these
nanoscale
polycrystals
work
and what
makes
them
both
durable
and functional," Rohrer
said.
To that
end,
MRSEC
researchers
have
discovered
that
materials
in this
polycrystalline
state
often
behave
differently
depending
on the
types
of grain
boundaries
they
contain.
Familiar
materials,
from
gold
to plastics,
display
startling
new properties
when
the nanoscale
grain
boundary
structure
is altered.
Some
can display
greatly
increased
strength
or resistance
to corrosion
while
others
can turn
into
potent
chemical
catalysts.
What's
more,
Carnegie
Mellon
researchers
are finding
with
their
newly
developed
computer-controlled
experimental
methodology
that
they
can create
materials
for everything
from
fortified
car fenders
to more
fuel-efficient
aircraft.
"We
see our
research
ultimately
making
it possible
for manufacturers
to one
day produce
smaller,
faster
computer
chips
and safer
power
plants," Rohrer
said.
MRSEC
also
has extensive
collaboration
with
national
laboratories,
as well
as important
international
collaborations.
An important
feature
of the
educational
program
is a
Partnership
for Research
and Education
in Materials
(PREM)
with
Florida
A&M
University.
Carnegie
Mellon's
center
is one
of 29
centers
nationwide
supported
by the
MRSEC
program
with
annual
NSF support
of $52.5
