Effects of grain size and texture on stress corrosion cracking of friction stir processed AZ80 magnesium alloy
TL;DR: In this paper, the effects of grain size and texture on the stress corrosion cracking (SCC) behavior of friction stir processed AZ80 magnesium alloy were investigated, and the results showed that finegrained (FG) and coarse-grained(CG) specimens with the average grain size of 2.7 and 7.1 μm was obtained via friction stir processing (FSP) underwater and in air, respectively.
