It is good to see that scientists are working hard to better evaluate the effect of He bubbles in metals and alloys!
Sharing a very interesting new article showing unequivocally the influence of He bubbles in the strengthening behavior of Copper! By using shock loading, Lear et al. discovered that He bubbles totally collapse, leaving monoatomic He behind, which then impedes deformation and embrittles the material. A significant work for the advancement of He bubbles influence on mechanical properties!
On this context, we have also investigated before the influence of Ar bubbles in the mechanical behavior of WTaMoV refractory high-entropy alloys, showing that Ar bubbles also contribute to strengthening of the material.
