The goal of this research was to investigate the viability of the Electrical-Assisted Forming (EAF) process at the microscale and the effects associated with grain size specimen size, cold work and timing of applied current. This research provided further knowledge related to flow stress reductions due to the applied current and the extent that the EAF process improves formability. The flow stress reduction effect increased with decreasing grain size and was more significant for cold worked specimens. Also, when the current is applied at a certain strain value during testing compared to the beginning of the process, less of a flow stress reduction effect was observed. With miniaturization data scatter increases and it was also observed that the EAF process may reduce data scatter: therefore, EAF may be a viable process at the microscale.
