Abstract:

This report describes novel experiments developed to characterize electron-dislocation interactions in umnm-scale specimens via in situ transmission electron microscopy TEM and tensile deformations of mm-scale specimens with applied electric currents and cooling that decoupled Joule heating from the current. The TEM results showed no apparent electron-dislocation interactions at current densities up to 5000 Amm2 with single-crystal Cu, and the coupled-tensile testing results showed large current effects on the plastic deformation of polycrystalline Ti but no effects with Cu and Fe.
