Abstract
1.A change in the structure over the length of the wire, beginning at the terminal, is a basic structural indication of current overload; there is no coarse-grain segment in the vicinity of the burn zone.2.The magnitude of the overload can be estimated by comparing the distances from the terminal to the segments with the recrystallized structure and (or) burn; the higher the overload, the smaller these distances.3.A coarse recrystallized grain near the burn zone and an extended region with a partially recrystallized structure are indications of local external heating.4.A finer grain in the burn zone as compared with the coarse-grain structure of the recrystallization zone is an indication of an overload that precedes heating to 600°C.
