The magnetic aftereffect of steels of technical purity containing C and N interstitials was calculated supposing a Snoek-type relaxation and the additivity of the two aftereffects. Some suggestions are made about the improvement of this approximation. The magnetic aftereffect of quenched and aged low-alloyed steels was measured. The ratio N/C after quench can be qualitatively determined from the shape of the curves of the aftereffect. The effect of aging (the change of the amplitude of the aftereffect because of the change of C/N and C + N) can be understood approximately on this basis.
