Conclusions
-
1.
High-Cr steel of Kh25-type is susceptible to deformation aging. This tendency is stronger when the interstitial element concentrations and the aging temperature are higher.
-
2.
A reliable method to study the deformation aging processes is to measure the metals' electrical resistance. Unlike other methods, this is nondestructuve and makes it possible to detect early stages of the process.
