How does an alloy combine aspects of both crystal lattice and a sea of electrons

•Metal bonding can be described as the sharing of free electrons between a lattice of positively charged metal ions. The structure of metal bonds is very different from covalent and ionic bonds. Ionic bonds bind metals to non-metals, covalent bonds bond non-metals to non-metals, while metallic bonds are responsible for the bond between metal atoms.

Hope this helps

the dissolution of polymer can be thermodynamically described in 2 steps.
