The results show that the cyclic softening is featured in bothvariedly hardened steels under strain controlled in the amplitude range of Δε_t,/2=0.6 - 1.8×10~(-2). The softening effect is mainly gathered in the prior some cycles.And the stress amplitude varies slightly in the sequential cycles, i. e. the softeningeffect is minified. No obvious saturation phenomenon of stress is observed duringthe whole cyclic deformation. The cyclic softening was analyzed under TEM thatit is related to heterogeneity of plastic deformation. The softening of the steelstested is caused by the formation or the dislocation cell structure with low densityand low internal stress, and by the redissolution of fine carbides into matrix.
