Thanks very much for this! Was using this to characterize grain structure of Babbitt (tin alloy) fabricated by Liquid Forging, and compared it with TIG based additive manufacturing of the same material!
The difference you got in the two methods results from counting the leftmost grain as 1 in the intercept method, when it should've been counted as 0.5. In the Intersect method it was assumed that the left end of the line ends in that grain. If there was another intersect at the left, then that would add 1 in the intersect method and also in the intercept method, since then the line ends in the next grain i.e. the 0.5 becomes a 1 and theres another 0.5. If the line ends exactly on a grain boundary, then in the intercept method that first grain is counted 1 and there's no 0.5 for the line ending within a grain, and in the intersect method the first cut should be weighed with 0.5 to make it consistent. The 1.5 for a triple point in intersect is consistent with going through one more grain and an added tangential in intercept. So if a triple point in intersect is classified as tangential to one of the three grains in intercept the results should match.
what if we want to use for dendrites? like eutecitc snBi microstructure and want to study phase size distribution. I'll be really thankful if you could help
What a really clear video, many thanks for sharing and taking the time Dr. Michael.
Thanks for watching. We're glad you enjoyed it!
I have definitely got something from the video...why do you have very few subscribers? You have such nice content.
thank you so much for this information, it's very useful and your way to explain is excellent, greetings from Mexico!
That is a really fantastic video, I really appreciate that. Thank you Dr. Michael

Great teacher Great video 👍
Metal for life🤘🤘🤘

Great Video ! I appreciate a lot, thank you !!!
Glad it was helpful!

Thank you
You should teach u are awesome
is this method for single phase and two phase ?
or there are methods for two phase ?
Only for single phase. There are methods for two phase written in the standards.
@@michaelshakib7777 coudn't find one even the E1881 doesn’t apply for my case (ferrite and carbides)
hey can you give me the litterature or source to me? because i never find linear method for intercept
i got sorry, thanks
can I use this method in zirconia grain size measuremnt?
for ceramics
If the grains are clear, and it is single phase then yes.
