-aged and T77 treated samples. When the precipitate is coherent with the Al matrix, the larger the precipitate is, the slower the fatigue crack grows. The effects of grain boundary precipitates and precipitate free zone on the fatigue crack growth resistance are less significant than those of precipitates within grains of the alloy. Key words: 7055 aluminum alloy; ageing; fatigue crack growth rate......
