Fine-grained polycrystalline specimens in tension at 77 deg K were strained to a prestrain E/sub p/. The specimens were aged at a temperature T/sub alpha / for a time t/sub a/ and the tensile deformation at 77 deg K was continued. Upon continuing deformation after aging, a yield point was observed and the magnitude was defined as DELTA sigma . Good results are obtained if DELTA sigma is assumed proportional to point defect concentrations along the dislocations. It is indicated that the defeat causing the strain aging is the interstitial and that appreciable concentrations of.interstitials are produced by plastic deformation. (L.N.N.)
