Ultrasound is used to study the production and annealing of the diaelastic effect in Fe. Frenkel pairs created by 2.3-MeV-electron bombardment cause the shear moduli, [ital C][prime] and [ital C][sub 44], to soften by ([minus]27[plus minus]2)% and ([minus]17[plus minus]4)%, per at. % pair, if resistivity per at. % pair is 20 [mu][Omega] cm. Smaller diaelastic effects were expected theoretically, given the high migration energy of self-interstitials in Fe. The magnitudes are of the same order as for Cu, but the observed anisotropy matches that detected in Mo, the only other bcc metal tested.
