Study on the Fatigue Small Cracking Behavior of 6A02 Aluminum Alloy

Abstract:

This paper is to reveal the small crack growth law of 6A02 aluminum alloy specimen by SEM in-situ experiment. The Nisitani H. formula for crack propagation is modified by SEM in-situ experimental results. The effect of corrosion is emphasized in small crack growth law of 6A02 specimen by introducing of corrosive factors. The fitting curve between corrosive factors and corrosive time is revealed. It would provide a theoretical foundation for the corrosion fatigue damage of 6A02 aluminum alloy.
