Hydrogen induced defects in annealed and plastically deformed pure aluminium have been studied mainly by the positron lifetime method and the transmission electron microscopy.It is revealed that the hydrogen charging can introduce blisters and dislocations in aluminium specimens.Inclusion particles in the specimens act as the nucleation sites of hydrogen induced defects. The effect of protons to shield defects from positron has been proved by the experimental results.
