CORRELATION BETWEEN AGEING HEAT TREATMENTS, MICROSTRUCTURE AND STRESS CORROSION PROPERTIES OF Al-Li-Cu-Mg ALLOYS
Overview & Synopsis
Stress corrosion cracking (SCC) behaviour of 8090 alloy (Al-Li-Cu-Mg) has been studied using precracked double cantilever beam (DCB) specimens and tuning fork type smooth test specimens. The alloy was SCC tested in several ageing conditions. Although stress corrosion cracks readily initiate when the alloy is exposed to 3.5 % NaCl environment, crack growth is difficult. The SCC performance of the 8090 alloy has been compared with that of 7075-T651 alloy. Fracture toughness of the alloy in a variety of ageing heat treatment conditions was determined by using chevron-notched short bar specimens. Ageing response of the alloy has been determined by hardness measurements and electrical conductivity measurernents.
