Part 3/7:
When atoms transition from one arrangement to another, it is known as a phase change, a phenomenon that can be observed in common materials, most notably water, which transitions through solid, liquid, and gas phases. Interestingly, many other materials exhibit multiple phases as well.
The Magic of Shape Memory Alloys
When discussing shape memory alloys, the term "remembering shapes" reflects their unique ability to revert to specified arrangements of atoms, effectively changing their physical shape. These alloys undergo distinct phase changes that allow them to switch between forms.
