Technical Support Package for Tech Brief 68-10534. Improved Thermal Treatment of Aluminum Alloy 7075

Abstract

The mechanism of the stress corrosion cracking of high strength aluminum alloys has been investigated using electrochemical, mechanical, and electron microscopic techniques. Corrosion and stress corrosion experiments have been carried out in 1M NaCl buffered to pH 4.7 at 30 deg. C, using the commercial alloys 7075 and 2219 and also relevant pure materials. The feasibility of detecting stress corrosion damage in fabricated aluminum alloy parts by nondestructive testing techniques has been investigated using ultrasonic surface waves (Rayleigh waves).
