AbstractThis paper is concerned with an analysis of the variation of flow stresses with the frequency of twin boundaries present in the microstructure of copper and austenitic steel. The increase of the frequency of twin boundaries results in a reduction of the flow stresses. This effect is explained in terms of dislocations being generated at the twin boundaries. The source of the dislocation generation from these boundaries was found during in situ strain experiments under the transmission electron microscope. The direct observations of dislocations generated from twin boundaries are presented in the paper.
