摘要：
The magnetic properties (magnetization, coercive force) of ferritic-martensitic steels EK-181 (low-activation, Fe-12Cr-2W-V-Ta) and ChS-139 (Fe-12Cr-2W-V-Ta-Mo-Nb-Ni) have been studied. The steel samples were subjected to different heat treatments and irradiation with neutron fluences of up to 5 x 10(19) cm(-2) (E-n >= 0.1 MeV) in an IVV-2M nuclear reactor at a temperature no higher than 70 degrees C. Within the limits of the experimental error (similar to 1%), the heat treatment and neutron irradiation have almost no effect on the magnitude of the magnetization of these steels. Neutron irradiation leads to an increase in the coercive force of steels up to similar to 50% depending on the regimes of heat treatment and neutron fluence.
