Calculate amount of ferrite in a sample.

[ladil]

Hello,

I have a mounted specimen that I have etched.
I need to make a calculation/estimation of the amount of ferrite in the sample.
How do I do a simple analysis?

Thank you

You can estimate the concentration of ferrite in your sample by doing an areal analysis of your sample. You can do this by capturing a magnified image of your sample surface (taken from a microscope), and then using any of the many areal analysis software tools out there. An example of such software can be found here:

You can also use a line analysis instead of an areal analysis - where you draw a line through the captured image of your sample, and measure the length of your ferrite phase relative to the overall line length.

Implicit in these two methods is the assumption that ferrite concentration is uniform throughout your sample.
