This tutorial is one of many instructional videos
presented by the Olympus Industrial Equipment Group.
This tutorial video will provide you with detailed instructions
to perform classification of non-metallic inclusions
in steel samples with accordance to industry standards
within the Olympus Stream Image-Analysis software.
Non-Metallic Inclusions influence the mechanical properties of steel.
Too many, or too severe, may result in steel
becoming too brittle, fragile or easily broken.
Because inclusions have such a profound influence on the finished product,
it is of importance to accurately detect
and characterize their presence.
The non-metallic inclusion solution is an add in module
for Stream Essentials and above.
To begin capture a greyscale image of non metalic inclusions
that lie horizontally, or parallel to the rolling direction of steel
within the OLYMPUS Stream software.
For clasification and evaluation of the image
we should be in the "Processing" tab.
To open the "Materials solution" tool window
we can right click in an open area within the tool bar,
then select "Tool Windows."
Within "Tool Windows" we then need to select "Materials Solutions."
Within the "Materials Solutions" tool window we will choose
"Inclusion Worst Field" to start that specific solution.
Once the "Inclusion Worst Field" window opens
it will start with the "Image source" selection,
the option to load our settings,
and the ability to skip the sample information section.
At the top of the window we will have "Instructions"
that will guide us through each screen,
and at the bottom we have the work flow list of this solution.
The image source selection can be from a new live image,
the selected image already opened within the software,
a batch of images located within a system folder,
or a batch of images we select within the optional OLYMPUS Stream database.
The ability to process multiple images as a batch
will increase workflow and allow us to average data
over a group of images associated with a single sample.
Opening our settings at the start of this process
will allow us to utilize standard values
to increase repeatability in your measurement results,
and also decrease your processing time.
Click on the next arrow icon at the bottom
to move to the "Sample Information" section.
Within "Sample Information" we have the ability to provide
titles or names to the part or sample,
provide a title for our group of images,
give detailed comments for that group of images,
and also provide detailed comments for each
individual image being processed for the sample.
Click the next arrow to move onto settings.
Within settings we can select the "Evaluation Method,"
set our Threshold values, and choose to show the ignored particles.
Inclusion Worst Field solution utilizes the following evaluation methods.
We will be using one of the more common methods,
"ASTM E 45 method A" for this demonstration.
Within settings we have the ability to adjust the threshold values.
The first threshold to adjust is for all inclusions,
move the threshold slider so that both darker oxides
and brighter sulfides are detected.
After setting the final value for threshold on all inclusions,
we will then need to set the threshold specifically for oxides.
Since oxides are slightly darker than sulfides
this value will be lower than the last,
but we still have to make sure to include all levels of oxides
within the red overlay from adjusting this threshold.
Once we have the threshold values set for both inclusions
we can click on the next arrow to move to "Image Results."
This window will display a table with the measurement results.
In it, we find the largest inclusion of each type.
The appearance of this classification depends on the standard
by which the analysis was performed.
The "ASTM E 45 Method A" standard that you used
sets the classification A (Sulfide),B (Alumina),
C (Silicate), and D (Globular Oxide).
Furthermore, this standard groups the inclusions into
"t" (thin) and "h" (heavy ),
according to their mean width (inclusions type A, B, C)
or to their diameter (inclusions type D).
At this point we also have the ability to reject this image
as it may be out of spec, and not have it's data
weighed with any of the batched images we may have.
We can also edit the inclusions by either linking them,
separating them, changing their type, or deleting them.
Select the delete tool here.
Now find any inclusions that need to be removed
and select them for deletion.
When finished with deleting simply right click to exit that function.
Click on the next arrow to move onto our results.
Within the results window we will see the sum of the method we used.
We also have the ability to select to generate a "Report" and a "Workbook."
The save settings to file button allows us to save all the selections
and thresholds we made for this entire process and then load it
at the beginning when you start the Inclusion Worst Field solution again.
This provides a more repeatable method for the process of like samples.
Click the next arrow to move on to setup of our report
since we placed a checkmark in the box above.
We now have the ability to select our report template.
We can use the default template,
or generate our own custom template through "Microsoft Word"
and then select user template and point to the folder
where our user template is located.
Below is the choice of content,
leave all selected to show your results.
Now click on the "Finish" button to generate the report
and output the workbook as we had selected.
Within the first page of the report document
it will show the overal sample summary.
The second page shows the summary result for each sample image,
we only had one image selected for this demonstration.
The last pages will show the detailed results of each image,
with the captured image showing the overlay.
Now switch back to Stream.
Click on the tab labeled "Workbook01"
at the top window to view our results.
The first page is labeled "Summary" as shown on the lower tab.
This page displays the results of the overall sample analysis.
Click on the second tab within this workbook labeled "Sample 01."
This shows the details of our individual image results.
If we had a batch of images for this sample they would be listed here.
For this demonstration we only selected a single image.
This workbook file can be saved within the database,
or you can export it to excel.
In this instructional video, we have covered classification of non-metallic inclusions
in steel samples within the Olympus Stream Image-Analysis software.
