摘要

Alternate immersion stress corrosion testing according to ASTM specification G44has proven to be representative for aluminium alloys in natural environments resembling the actual environmental conditions for aircraft. A simple automated stress corrosion testing method called the ASCOR (Automated Stress COrrosion Ring) test was developed to test aluminum alloys according to the specification. The method involves testing cyclindrical or sheet specimens in a loading ring provided with strain gauges to measure the load. Initiation of a stress corrosion crack results in a small load decrease. During the test the load is measured periodically and stored in a Data Acquisition system controlled by a Personal Computer.
