The determination of tendency to deformation aging for cold-worked products has
its own specifics, which is partially covered in the work [26]. Here we note only the
following main differences from the standard specifics.
1. The degree and the scheme of the cold deformation are not actually conditional,
but are specified by the deformation parameters for manufacturing a cold-worked
object-product. 2. Deformation aging should be carried out as a stress deformation
aging (based on the operating conditions of the product), duration and temperature are
set, as the relevant statistics are gathered for the products of this class. 3. The same
statistics are needed to determine the permissible values of properties of the
deformation-aged product, under which the process of deformation aging of the
product during operation in a given time interval does not lead to a loss of the load-
bearing capacity of the product. 4. It is also clear that the deformation aging of the cold-
worked product according to the described scheme and its results are closely related to
the possibility of adjusting the tendency to deformation aging in one way or another
[26-29].
Figure 1 below graphically presents the developed variants for the technological
schemes for manufacturing steel products hardened by cold deformation with the use
of the new principles for the formation of structural states with a high density of linear
and two-dimensional defects of the crystal structure.
