comment The physics behind Google Glass' “prism”
I imagine they are made bespoke for Google. You can certainly get prisms bonded together like that for beamsplitters but the polished convex (concave on the inside! :) ) surface is almost certainly patented. Any decent optics supplier is likely to have prism assemblies and mirrors e.g. Thor Labs, Newport, Edmund Optics - to name but a few.

comment Eutectic systems behavior near 100%-0% composition and low temperature
As you cool down into the two phase region the A-rich crystal can no longer hold the B in solution. The B will start to diffuse out of the A rich crystals and form new B rich crystals. This will normally happen at the grain boundaries and so you end up with lots of tiny B-rich crystals around the larger A-rich crystals. This does indeed all happen in the solid phase. Even in a solid, atoms can diffuse around the lattice. But if you cool faster than the atoms can diffuse you can force a material into a single phase. But then the standard phase diagram in the original question would not apply.
