The aluminium alloy is the second-largest alloy being used in the world next
to steel. Aluminium exhibits good mechanical strength, resistant to corrosion and
lightweight. But due to some environmental variations or conditions, the alloy was
found to be prone to cracking. The microstructure cracking is due to many factors like
corrosion, mechanical stress, thermal stress, and bacterial adherence. The Sulfate
Reducing Bacteria (SRB) is the most active bacterium, which causes rusting. The
chloride ions present around the aluminium alloy led to corrosion and the failure of
microstructures in the alloy.
