| Popis: |
Fatigue crack growth behaviour of high strength aluminum alloys for aircraft components was studied experimentally in relation to testing environment. Crack path was mainly transgranular. Crack growth rate was slightly larger in 7075-type alloy with higher fraction of intergranular path than 2024-type alloy, when tested in moist air. The rate of the 7075-type alloy was decreased by changing the environment to the flow of nitrogen gas. In moist air, hydrogen embrittlement based on intragranular cracking has been known to occur in 7000 series alloys. Thus, the large fatigue crack growth rate of the 7075-type alloy as attributable to hydrogen embrittlement. |
