Abstract The development of acoustic emission during tensile tests of specimens taken from the shells and bottoms of large fuel tanks made of an AMg6 alloy after long-term (for about 30 years) operation is investigated. Different technological states of the structural elements of a tank (cold working of the shell and annealing of the bottom) are shown to affect the acoustic parameters. The activity of acoustic emission signals are found to decrease during the destruction of the cold-worked material and in the specimens oriented across the rolling direction.
