Nature of strain hardening of PKh23N18 corrosion-resisting powder steel

Conclusions The temperature dependence of the yield stress of PKh23N18 corrosion-resisting powder steel is nonmonotonic. The formation of the maximum on the curve in the range 575–795°K is determined by the interaction between the dislocations and the carbon atoms. Dynamic strain aging of PKh23N18 steel in the temperature range 795–925°K is controlled by the chemical interaction between the split dislocations and chrome atoms.Translated from Poroshkovaya Metallurgiya, No. 1(277), pp. 86–91, January, 1986.
