An Investigation of the Scatter in Variable - Amplitude Fatigue - Test Results of 2024 and 7075 Materials
نویسنده
چکیده
SUMMARY The scatter in the fatigue lives of identical simple laboratory specimens, which have been tested under variable amplitude sinusoidal loading, is estimated, using a log-normal distribution of fatigue lives as a basis, from the fatigue test results of a number of experimenters. These estimates of the scatter are analyeed with 8 view to studying the effect of various teat loading parameters on the magnitude of the scatter produced and the results of this analysis are then discussed in terms of a simplified model of the mechanism of fatigue failure.

Strengthening Mechanisms in the Aged 2024 and 7075 Aluminium Alloys
Aluminum 2024 and 7075 alloys which are widely used in aerospace and marine applications were chosen to investigate their strengthening mechanisms. Using differential thermal analysis (DIA), metallography and tension tests, the best solutionizing conditions were determined to be 500±5°C and 2 hours for 2024 and 480?±5°C and 1 hour for 7075 alloy. Aging was performed in the range of 100 to 200°C...
