After ageing low carbon steel specimens, given tensile, torsional or tension-torsion combined prestrains, the tensile stress-strain curves or the torsional stress-strain curves at various angles to the direction of prestrain were obtained, and from these curves 0.03% elastic limits and 0.2% yield strengths were determined and the activation energies in the rising process of these elastic limits and yield strengths were obtained. It is clarified from these results that the sharp yielding phenomena in low carbon steels recovered by ageing and the activation energies in the rising process of the elastic limits and yield strengths in various directions to the prestrain are very closely related to the ainisotropy of the Bauschinger effect in the specimens caused by the prestrain.
