Effect of Extension Rate on Stress Corrosion Cracking Velocity Using Electrochemical Noise Analysis

In this work, the experimental results of nucleation, growth, and crack propagation susceptibility in aluminum 2024-T351 are studied. The experimental results were obtained from the constant extension rate test technique using three different extension rates (1X10-6mm/s-1, 2X10-6mm/s-1, and 7x10-6mm/s-1). Electrochemical noise analysis was also used. Scanning electron microscopy (SEM) images showed that the two concentrations of NaCl did not...
