Abstract:
Stress-relaxation data in Inconel 718, both at 773 and 823 K and up to times of the order of 4000 h, in specimens with different thermal treatments, are presented. No substantial differences are encountered, between 773 and 823 K, in the stress-relaxation behaviour of the age-hardened material. In the as-received and the solution-annealed specimens, on the contrary, the stress-relaxation curves indicate that the structure does not remain stable during relaxation and the internal stress decreases continuously as the applied stress decreases. The structure is stable, for all the thermal treatments, during stress relaxation at 773 K. Finally, the data are interpreted in terms of an interaction between gliding dislocations and precipitates as indicated by the large activation volumes involved and the negligible influence of thermal activation. © 1988 Chapman and Hall Ltd.
