โœฆ Synopsis

Abatraet-A method of measuring stress corrosion crack growth rates in an aluminium alloy, using contoured double cantilever beam specimens, is described. Samples taken from these test pieces and examined under an optical microscope suggest that there are two distinct mechanisms of crack growth. At stress intensities below about 0.85KIc, exfoliation corrosion occurs within the crack, producing a zone of damaged material of finite thickness, rather than a single crack. At very high values of K,, a process similar to "fast fracture" occurs.

The aluminium alloys exhibit, when submitted to certain aggressive conditions, a particular corrosion feature named exfoliation, leading to the formation of thin laminar corroding foils. Three different alloys having distinct corrosion features; 2024 T351, 2219 T87 and 6013 T6 were immersed in the E

Crack extension in some high strength aluminium alloys was investigated using acoustic emission measurements. The tensile ductility varied with prior heat treatment and was strongly correlated with the volume fraction of coarse intermetallic particles retained in the structure. The acoustic emission
