1. The grains size gets smaller on the alloy surface with A concentration increasing, which may be due to the following two sides: one is probably that A can reduce the grain size; the other could be that the nucleation and growth is in competence. In larger current, the nucleation is easy to break out and its velocity exceeds the growth speed of grain, so the grain cannot grow and gets smaller.
2. It seems that A and B elements are distributed more densely.
