Abstract

Transmission electron microscopy was used to study the details of deformation twinning in Cu-8.7at.%Ge subjected to extremely short duration stress pulses generated by shock loading. In addition to providing information about the twinning mechanism and its time dependence, the study established that twin boundaries are about 1% as effective as grain boundaries in strengthening. Twins were shown to form in less than 0.020 μs in the alloy, while the rate of dislocation generation is also high, of the order of 10²¹ m^-2 s.
