Molybdenum specimens with differing grain sizes but similar sub-grain sizes were irradiated to an epithermal neutron dose of approximates 2 x 10/sup 18/ nvt and their yield stress measured. The plot of the data versus (2d)/jsup - 1/2/, where d is the grain diameter, shows that the yield stress is not independent of grain size; hence, the hypothesis of sub-boundaries being strengthened by irradiation is not correct. It is noted that the irradiation hardening is approximately the same as that observed previously for a dose ten times as large. (D.L.C.)
