Grain Boundary Sliding,riments for Cu. The most import effect of GBS is that it gives rise to the initiation of creep cavities, Chap. .. GBS is also the main mechanism for superplasticity. A basic model for superplasticity is presented.

Scott Davidson,Marc-Antoine Vallée the literature it is frequently assumed that dynamic recovery is controlled by cross-slip. However, the measured activation energy for dynamic recovery is many times smaller than the energy required to make partial dislocations brought together and form a constriction, which is necessary to enable cross-slip, so this is an unlikely possibility.

Solid Solution Hardening,es give rise to a drag force that slows down the motion of the dislocations. Fast diffusing elements have to break away from the dislocations to enable their motion. This creates a break stress that is the source of SSH in this case.

Precipitation Hardening,articles larger than a critical size have to be passed by the Orowan mechanism, because there is not time enough for dislocations to climb across these particles. This mechanism was finally verified for Cu–Co alloys.

: The Film World as Representationr creep deformation and cavitation, the rupture stress and ductility can be predicted. Several models exist for the influence of multiaxiality on the creep ductility. Although the models are based on different principles, they predict approximately the same behavior, which is verified by comparison to rupture data for notched bars.
