摘要：

The crack-growth behavior of a nickel-base HASTELLOY X superalloy was investigated under fatigue, creep, and hold-time test conditions at 816degreesC and 927degreesC. The hold-time tests were conducted with 2-min. and 1-hr. holds. It was found that the fatigue crack-growth rates could be correlated with the stress-intensity factor range, DeltaK, and the creep crack-propagation rate can be related to the stress-intensity factor, K. The crack grew faster at a higher temperature. It was also noted that the introduction of a hold time at the maximum load led to an increase in the cyclic crack-growth rate. The longer hold time gave the faster crack-growth rate. The crack-propagation rates in the hold-time tests were predicted from the crack-growth rates obtained from both the fatigue and the creep crack-growth tests, using a semi-empirical linear summation model. Crack-growth rate predictions reproduce most of the characteristics observed experimentally.
