Effects of master alloy of quasicrystal containing magnesium additions and solution treatment on microstructure and mechanical properties of AZ91 magnesium alloy were studied.
The metabolism of hydrogen which involved hydrogenase was the main reason for the MIC of AZ91 alloy.The SRB accelerated the cathodic reaction through the cathodic depolarization.
But, throughout the 20th century, other methods were explored: the AZ Pregnancy Reaction Test popped up in 1928 and was the first of several " bioassays" or animal-based tests.
