本文测定了多晶Al在恒应变循环变形下的循环硬化曲线和循环应力-应变曲线,并用透射电镜(TEM)观察了相应的位错亚结构。本文着重探讨循环变形与位错组态的关系及晶界在循环变形中的作用。
The cyclic deformation behaviour of Al polycrystals has been investigated at constant plastic strain amplitudes, γ_(pl), over a range 2×10~(-5)<ε_(pl)<4.7×10~(-3). The cyclic hardening curves and the cyclic stress-strain curves were measured and correlated with the change of dislocation substructure in grains and grain boundaries. In this study, an effort.was taken to explore: @1. the change of dislocation substructure as a function of the number of cycles; @2. the effect of the strain amplitude on the dislocation substructure in saturation; and @3. the role of grain boundary in the cyclic deformation.
