Abstract
The results from TEM study of helium porosity in nickel samples, irrad iated to a fluence of 2 x 10(21) He+ m(-2) with 12 keV helium ions, an d subjected to isothermal annealings for 0.5h at 850, 950, 1050 and 11 50 K, are reported. The experimental evidence for the dependence of he lium porosity evolution in the implanted layer on vacuum conditions at which the samples are annealed, is presented. It is shown that on ann ealing in oil vacuum the temperature of the stage of intensive bubble growth is 300 K lower as compared with the one on annealing in oil-fre e vacuum.
