Can this page be expanded to include sub-grain boundaries or should that be a separate page? What is the difference between a low-angle grain boundary and a sub-grain boundary? Mikenorton 20:32, 14 October 2006 (UTC)
Oops, haven't been keeping up with wikipedia for a while. Sub-grain is a synonym for low-angle so the article already discusses them. I ought to make that clear. What this article really needs are subsections or other pages discussing the practical and industrial aspects of the properties of boundaries. Slinky Puppet 19:59, 18 January 2007 (UTC)
I've been discussing the etymology of the term "grain" and "grain boundary" with a colleague, and was diappointed not to see the answer here. Does it come from the "direction" (as the "grain" of wood), or "kernal" definition? Or rather, is it a translation from another language (i.e. "Korngrenze" in German)? I see historical sections on other more prominent discoveries, but it seems that everyone has taken this set of terms for granted.126.96.36.199 (talk) 20:50, 5 May 2014 (UTC)
