Abstract
The behavior of metallic materials subjected to short-duration heating resulting from the passage of high currents is investigated. Specifically, direct experimental measurements are made of the stress drop and recovery engendered by the application of a 1-ms-long current pulse that raises the temperature of the specimen to about 450 K. The experimental results are used to calibrate an adiabatic viscoplastic model describing the material behavior
