The Use of Slow Strain Rate Technique for Studying Stress Corrosion Cracking of an Advanced Silver- Bearing Aluminum-Lithium Alloy

摘要

In the present study, stress corrosion cracking (SCC) behavior of naturally aged advanced silverbearing Al-Li alloy in NaCl solution was investigated using slow strain rate test (SSRT) method. The SSRT's were conducted at different strain rates and applied potentials at room temperature. The results were discussed based on percent reductions in tensile elongation in a SCC-causing environment over those in air tended to express the SCC susceptbility of the alloy under study at T3. The SCC behavior of the alloy was also discussed based on the microstructural and fractographic examinations.
