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.

AMg6合金燃料箱结构元件材料的工艺状态对声发射参数的影响。

摘要

研究了在长时间（约30年）运行后从由AMg6合金制成的大型燃料箱的壳体和底部进行的拉伸试验中，声发射的发展。示出了罐的结构元件的不同技术状态（壳体的冷加工和底部的退火）会影响声学参数。发现在冷加工材料的破坏过程中以及沿轧制方向定向的试样中，声发射信号的活动性降低。
