Conclusions
-
1.
The distribution of structural deformations measured on a base of 10 and 20 μm for steel 1Kh2M with a grain size approaching 20 μm is characterized by the normal law over the entire temperature interval investigated (20–700 °C).
-
2.
The dimensions of the region of the mutual effect of microvolumes as determined from the behavior of the autocorrelation function of structural deformations diminish with test temperature; this is accompanied by activation of the mechanism of intergranular deformation.
