Ok, so maybe this shouldn't be shown in class.
I've long wondered how single crystal turbine blades are grown to be single crystals. We mimic this is far less complicated ways with our copper (II) sulfate crystal growth lab in our matsci class at Princeton (and in many other ASM-born matsci classes).
...but I knew that simplistic method clearly wasn't going to work for the cast metal structures for metallic crystals.
Thankfully this video's foul-mouthed Yorkie host explains how we go from molten metal to single crystal, grain-boundary-less macrostructures. It's not a very thrilling video as it's just a knowledgeable guy explaining things in his garage with a white board to show what he's talking about. I respect the knowledge and appreciate his explanation about something I've wanted to know for a while now.
Maybe just watch it and explain things to your students rather than showing the video itself.
...because the video itself is absolutely fandabidozi.
