Observing the changes of the edge a bit grainy and belongs to the atom. Note in the phase of triangular phase because it has characteristics closest to the most solid. And this is something that happens over time.
Observing the change of the grain boundaries and the probability of an atom. Be observed in the phase of the triangular phase because of its close proximity to the most solid. And this is what happens over time.
Observing the change of grain boundary, and the probability of the atom is observed in the phase of triangular phase because looks similar to most solids And this is what happens when time passes by.
