The effect of electron irradiation on the microyield stress was investigated in ZrH$sub 2$ purified Battelle-AISI iron single crystals at 4.2, 30, and 60$sup 0$K. The irradiation caused a hardening effect which increased with the electron dose. This hardening effect in the microyielding is opposite to the observed softening effect in the macroyielding. These observations can be satisfactorily explained by the interaction of the irradiation-induced interstitials with edge and screw dislocations, respectively. The present observation is also regarded as strong evidence supporting the theory of an intrinsic mechanism for the low temperature strength and the solid solution softening in iron. (auth)
