Book Description
Stress-corrosion cracking experiments have been performed on double-cantilever-beam specimens of 7079-T651 aluminum in 3 percent sodium chloride in distilled water and in seawater. At relatively low-stress intensities (Region I of the crack-growth rate/stress-intensity plot) crack length versus exposure time curves were comprised of steps, plateaus, and straight-line segments. These could not be related to any variations in the stress-intensity parameter; so, where such behavior was encountered, no unique relationship between stress intensity and crack-growth rate was apparent. On the other hand, crack-growth rate did vary inversely with exposure time for the range 25 to 200 h. Such an observation was interpreted to mean that properties of the local environment within a crack control extension rate.

The Influence of Testing Parameters on Stress Corrosion Crack Growth in the High Strength Aluminium Alloy 7010-T651

Languages : en
Pages : 60
Book Description
An interlaboratory testing programme to evaluate the rising displacement test for stress corrosion crack (SCC) growth investigations was carried out within the framework of the "Measurements and Testing" programme of the European Community under BCR contract nr. MATI CT 930038. The contribution of the NLR to the project consisted of testing of precracked Double Cantilever Beam (DCB) Specimens made from the high strength aluminium alloy 7010-T651 under constant displacement and by continuous immersion in substitute ocean water. The results of these static tests were to be used as reference data for the dynamic rising displacement tests carried out by other participants in the project. Further, additional static tests were carried out by the NLR using alternate y. Duriimmersion in substitute ocean water. The results of these tests were compared with those of 7010-T651 plate from another batch of material tested previously at the NLR.
