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!

The thematic axes program is an endeavor of the Universidade de Sao Paulo, started in the present year and has the aim to provide institutional responses of the major university in Latin America in 11 important themes: Agriculture, Inequality, Democracy, Cities, Culture & Art, Education, Economy, Energy, Industry, Environment and Health, in view of the United Nation’s Sustainable Development Goals.
I am included in the thematic axis Energy and I am there mainly to represent Nuclear Energy, last Thursday, however, I attended another action of the group ..read more

Nanomaterials are offering unique opportunities for the design of future nuclear materials. In our recent paper at ACS Applied Nano Materials, we demonstrate that AISI-316 steel nanoparticles are capable of self-healing from the deleterious effect of heavy-ion collisions.
We also pose a new question to the materials community on the recyclability of potential nuclear nanomaterials.

In the late eighties and early nineties, the ETH Zürich researchers worked intensively on the development of high nitrogen steels at the Institute of Metals Research – with some success. The result was important patents with industrial partners. A number of such steels are still in use today, in particular the nickel-free austenitic steels used […]
