Pitting corrosion of rheocast A356 aluminium alloy in 3.5wt.% NaCl solution
TL;DR: In this article, the microstructure and corrosion behavior of rheocast and gravity-cast A356 aluminium alloys were examined and compared, and it was shown that large potential differences between iron-containing intermetallics and the α-Al matrix were responsible for the initiation of the attack at the intermetalics/α-Al interfaces.
