Folks generally don’t know what metallography is (an art form? a record collection? a synonym for molybdomancy), and even when I try to explain (in those cases where they care to know or feel etiquette demands they enquire), it’s often hard to imagine visually what I’m talking about. Leica Microsystems has published a fine introductory article to metallography with pretty pictures that should help y’all visualize a bit better what I do for a living.
On a side note, I met the author of the article when I worked for Nanosurf and he distributed our microscopes. When I left, he expressed some envy that I was moving into metallography, a field he loved. It’s great to see him back with passion!
