Stress-corrosion data have been obtained from specimens cut in the long transverse direction from an aluminium alloy extrusion to specification D.T.D. 5044. The specimens were prepared for test in such a way as to provide examples with approximately zero residual macrostress and increasing levels of microstress. Results from the stress-corrosion tests show that the addition of microstresses arising from cold work has had no effect on the stress-corrosion properties of this alloy.
