Talk:Scheil equation

Please explain fs and fl
I am trying to read into this subject, but don't understand the figure and especially the statement fs + fl = 1. This is probably due to me missunderstanding f.

(Unfortunately non of the books available to me, describe Scheil's equation and the paper, in which I found it, does not go into detail.)

Can somebody please define it, and better yet, explain a little bit to it. (Or point to another resource)

Thank you very much, an active Wiki user, Superbirk (talk) 10:41, 5 November 2010 (UTC)

It appears that fs and fl are the fraction that are solid and liquid, respectively. This should be added to the page.
