The environmental effects on the low cycle fatigue (LCF) behavior of 2024-T351 and 7075-T651 aluminum alloys were studied at room temperature. The specimens were subjected to identical LCF tests at strain ratio R of ร1 and frequency of 5 Hz in three environments: vacuum, air and 1% NaCl solution of
Variable-amplitude fat@ue studies of 2024-13 ab&num alloy were performed to examine the effect of sheet thickness on fatigue crack growth rate retardation. Results indicated tbat the amouot of retardation increased with decreasing specimen thickness. This phenomenon was attrii to enhanced plastic st
The rates of fatigue-crack propagatmn for a h~gh-strength aluminum alloy (7075-T651) in a~ envaronment of D20 (99 98~ purity) at room temperature were determined and compared with data obtained in [ugh-purity argon and dastflled water. The results showed that D20 caused a ten-fold Increase in the ra
