Influence of deformation on the retention of helium in materials

Resumo

The influence of deformation on the retention of helium in samples of the chromium–nickel austenitic steel uniformly saturated with helium using bombardment with α particles in a cyclotron has been studied. It has been shown that, under certain conditions, helium atoms can be carried away by moving dislocations, which can have a significant impact on the removal of helium from material, exit to the grain boundaries and redistribution it over the sample volume.
