Conclusions 1. A residual deformation, which may differ significantly in terms of both magnitude and sign from the deformation caused by a single static loading, builds up in aging alloy ÉI437B under a combined (dynamic and static) load. 2. Metallographic and electron-microscope studies of alloy ÉI437B indicated that the structure of a specimen that has developed negative vibrocreep at room temperature is characterized by a hardening γ'-phase with rather large particle sizes as compared with that in a specimen having exhibited a normal vibrocreep curve. This may be caused, however, by a difference in the initial structure of the specimen material and may serve as an adequate explanation of negative vibrocreep. 3. At high temperatures, the path of the vibrocreep curves of alloy ÉI437B is normal in character.
