Yep - I paid $29.00 for that article and was a bit disappointed. I was hoping for more detail: that article has a single isotherm at 927°C that is not even the author's but "redrawn" from Itoh's work in 1999. I suspect Itoh's paper (Trans. Mater. JIM, 1999) has more detail in it (8 pages is the article length) but I've been unable to find it as a purchasable/dowloadable document. I have access to a local university that has the journal in its stacks, but that's legwork I was hoping to avoid by searching on-line. Thanks for looking, though.
