摘要：

Al-2.3wt%Li and Al-4.1wt%Mg-1.1wt%Li alloys were neutron-irradiated in JOYO, JMTR and RTNS-II with different types of energy spectra. The changes of He production by different neutron sources and of precipitates due to the isothermal annealing at 400-degrees-C were investigated by transmission electron microscopy (TEM). It was confirmed from TEM observations that He production by transmutation and the coagulation of He atoms after the annealing depend on neutron energy spectra used for the irradiation. It was also found that the addition of Mg to Al-Li alloy strongly suppresses the growth of He bubbles. Interrelations among precipitates, vacancies, He atoms and Li atoms were investigated, obtaining a reasonable coincidence between mutual amounts.
