Abstract
The brass foil with a protective layer formed on one side was deflected dur ing original corrosion in 1 mol/L NH4OH + 5 g/LCuCl2 solution. This was due to corrosion-induced tensile stress developed in the dezincification layer of the sample. The additive tensile stress grew gradually, and reached a s teady value of about 24.4 MPa, i.e., 20% of the yield stress of brass. (C) 1998 Elsevier Science Ltd. All rights reserved.
