We
recommend
that
you
download
the
most
recent
version (mims_gui.exe) which
is
a
self-installing
archive.
Just
double-click
on
the
file
and
it
will
install
a
GUI
that
performs
skeletonization,
triple
junction
identification
(line
follow),
image
stitching
and
distortion
corrections. Installation
instructions are
also
available
for
the
older
versions
of
the

together
with

description.
- Grain
Boundary Tracer for
windows machines
- Microstructure
Builder:
this
is a
package
of codes
for building
3D microstructures
based
on EBSD/OIM
input
(developed
for Unix
systems
only,
but a
Windows
version
is available).
This
package
was developed
primarily
by Joe
Fridy
(Alcoa)
and David
Saylor
(CMU,
NIST)
with
assistance
from
Tony
Rollett,
Kee-Young
Jung,
Steve
Sintay
and Abhijit
Brahme.
It uses
EBSD
maps
on orthogonal
cross-sections
as input
(for
grain
shape,
orientation
and grain
boundary
character).
The output
is either
a surface
mesh
or a
voxel-based
regular
grid,
with
crystal
orientations
specified
for each
grain.
The output
is intended
for use
either
for constructing
finite
element
meshes
or for
use in
grain
growth
codes.
Suggestions
for extensions
of the
capability
are welcome.
Only
single-phase
materials
can be
modeled
at present.
Two-phase
microstructures
are under
development.
To obtain
a current
version
of the
package,
please

of

- Optical
image map of
a 1 cm diameter
thermally etched
SrTiO3 sample
with grooves
grooves that
are not so
deep (~ 370
images, 640
x 480)
- Twenty
.jpg images
making up an
optical map
of a SrTiO3
sample
- Optical
images of thermally
etched SrTiO3
sample. There
are six separate
areas, and
in each are
there are 36
images that
overlap to
form a 6 by
6 montage.
The are labeled
bA_B, where
A is the row
and B is the
column. Row
1 column 1
is in the lower
left hand corner
of the montage.
The images
are in BMP
formate and
are 640 x 480
pixels. The
field of view
is approximately
570 microns
by 427 microns
and the offsets
between the
adjacent pictures
are 550 microns,
lateral, and
400 microns,
vertical.
- Optical
images of thermally
etched SrTiO3
sample. These
images are
just as those
above, but
were recorded
after removing
about 7 microns.
- Grain
Boundary Skeletons
from MgO Each
of the three
skeletons is
a stitched
montage of
196 separate
images from
the same section
plane of the
sample.
- Grain
Boundary Skeletons
from SrTiO3 Each
of the 10 skeletons
is a stitched
montage of
36 separate
images from
two parallel
section planes
of the sample.
- AFM
images of spinel 49
images making
up a seven
by seven montage
of AFM "error" images
of a thermally
grooved spinel
surface.
- Montaged
AFM images
of spinel Four
.jpg maps of
stiched areas
(each area
is made up
of 49 55 micron
afm error images
that are overlapped
~5 microns,
each with 512
pixels, and
was stiched
by hand in
power point).
The 4 areas
actually make
up part of
the first row
-- from left
to right they
are: 1, 2,
16, 17, but
the areas themselves
do not overlap.
There are also
3 images of
area1 that
were processed
in photoshop.
- BMP
versions of
the individual
AFM images
of spinel Each
file is labeled
N.zip, where
N is the area
number. Each
is a zipped
directory containing
49 images making
up a 7x7 region.
Individual
images are
55 micron afm
error images
that are overlapped
~5 microns,
each with 512
pixels.
- SEM
images of triple
junctions in
Fe 8% Si Steel,
and the skeletonized
versions of
each.
