Effects of various parameters on the fatigue life of Alloy 718

Conference ·
OSTI ID:5533580
A data bank from over 700 tests on several heats of Alloy 718 with various test parameters is used to show the effects of temperature, strain rate, hold time, grain size, mean stress, surface roughness, and thermal aging on fatigue life. Both strain controlled and stress controlled tests were conducted providing data from 10{sup 2} to 10{sup 9} cycles to failure. Empirical curve fitting of the data was performed using a multiple regression analysis performance. 9 refs., 13 figs.
