摘要：

The TEM analysis and dilatometric measurements of submicron grained nickel prepared by severe plastic deformation indicate that heating induces the transformation of nonequilibrium grain boundaries to relative equilibrium boundaries. These changes correlate with changes in the saturation magnetization. The nature of this dependence is discussed with respect to the existence of a thin distorted layer in the vicinity of the nonequilibrium boundaries of a submicron grained (SMG) metal.
