it otherwise would have remained pinned. This theory is supported by the EAF
square wave and cooling versus non-cooling tests in this work. In addition, prior
EAF tests with large currents coupled with short pulse durations and isothermal
tests are also in agreement with this theory.
• With respect to increased elongation before failure, it is theorized that the
applied current provides a sufficient energy to pinned or stuck dislocation
within the lattice such that it allows for the dislocations to continue moving
again. As a result, this reduces the local stress within the material's lattice and
delays tvhe process of void formation and fracture.
