Abstract
The Bauschinger effect has been studied in Cu, Al, Pb, Ni and Fe, after deformations between 1% and 120%. The strain associated with the effect is shown to be approximately proportional to the stress applied to produce work-hardening, divided by the elastic modulus. It is independent of grain size. Its small dependence on temperature is explicable in terms of a thermal component of stress. It is slightly dependent on purity. The results agree with those of other workers, but disagree with the predictions of existing theories. A possible qualitative explanation of the effect is suggested.
