Small Crack Growth

Experimental investigations of fatigue cracking behavior of LC9 aluminum alloy (AA LC9) subjected to elevated temperature were conducted with scanning electron microscope (SEM). Results indicate elevated temperature is important for the fatigue crack growth of AA LC9. Based on small crack growth, crack growth rate for AA LC9 is characterized.

Small Crack Growth

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.

Corrosion fatigue is a form of degradation subjected to combined damage of mechanical stress and corrosive medium, which is an issue in aircraft industry. Experimental investigations on prior corrosion fatigue cracking behavior of LY12CZ were conducted with scanning electron microscope (SEM). Results indicate corrosion damage is important for the fatigue small cracking behavior of LY12CZ aluminum alloy. The effect of corrosion pit on fatigue crack can be characterized by the depth of corrosion pit. Based on small crack, another way to evaluate crack growth rate for AALY12CZ is proposed.
