(ii) Deformation temperature exhibits a reverse effect of γ-irradiation. This may be attributed to the
annihilation of the irradiated defects.
(iii) The mean value of 80 kJ/mole of the energy for activating the deformation process is found to
correspond to the activation energy of grain boundary diffusion in aluminum alloy.
(iv) γ -irradiation can be find its useful application in improvement the strengthening parameters of
Al-5356 alloy.
