The paper reports on an experimental study of the possible application of acoustic emission as an inspection technique, to determine whether 2124-T851 aluminum plate meets certain, minimum, fracture toughness specifications. Unllawed specimens, taken in the three principal directions, from three sep
## Modal acoustic emission technique was used to analyze corrosion signals produced by polarization corrosion of LY12CZ aluminum alloy. The results showed that there were two-type waveforms for both anodic and cathodic polarization. Only extensional signals appeared within 1800 s, but extensional
