Conclusions
-
1.
The resistance of Cr−Mo−V steel to relaxation is high only when alloying with Cr ensures a low rate of diffusional processes.
-
2.
The highest strength and highest resistance to relaxation were found in steel in which the ferrite contained 0.5% Mo, 0.1% V, and 1 or 10% Cr.
-
3.
An increase in the amount of Cr in the ferrite from 1 to 5% is useless, since it decreases the strength and the resistance to relaxation because of the decrease of the energy of interatomic bonds in the lattice of the α-solid solution and increased diffusional ductility.
