Casting metallic alloys is a primary human activity since the ancient times. Now, by using advanced methods of electron microscopy coupled with the advent of micro-electromechanical devices (MEMS), Diego Coradini and Professor Stefan Pogatscher led a scientific team to a study that demonstrates the feasibility to cast metallic alloys at the nanoscale. Coradini et al. … Continue reading A New Era Beckons: The Epoch of Nanometallurgy

Maximizing corrosion resistance of aerospace aluminium with self-healing coatings
The use of sol-gel coatings to increase the corrosion resistance of commercial aerospace aluminium alloys is the topic of our most-recent paper at Corrosion Science. In combination with anodization treatment and the use of Ce nanoparticles to fill-in the pores of the anodic layer, we have observed that a post-treatment with sol-gel coatings further increases … Continue reading Maximizing corrosion resistance of aerospace aluminium with self-healing coatings
An entire life dedicated to nuclear radiation physics and mentorship
Professor Kenya Moore de Almeida Dias da Cunha was a Brazilian nuclear physicist who dedicated her entire life to the study of actinide materials and in the academic education and scientific initiation of the next generation of research scientists. She was a lovely and passionate experimental scientist -- to the best definition of the term … Continue reading An entire life dedicated to nuclear radiation physics and mentorship
The influence of He bubble in strengthening of Copper
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 … Continue reading The influence of He bubble in strengthening of Copper
New H-based materials for use in micro-nuclear-reactors
We just got a preprint available in arXiv.org for the general audience: "Fabrication of bulk delta-phase Zirconium Hydride from Zircaloy-4 for use as moderators in microreactors" (arXiv:2305.02249v1) In this manuscript, we performed a complete electron-microscopy characterization of the delta-phase Zirconium Hydride (delta-ZrH) currently under manufacturing, research and development to be used as moderator materials in … Continue reading New H-based materials for use in micro-nuclear-reactors

Amorphous and Refractory High Entropy Alloys
In this very interesting new field of research on refractory amorphous high entropy alloys (RAHEA), we present a case where two different RAHEAs have been synthesized and tested under extreme environments: the WTaCrV and WTaCrVHf. We discuss the parameters that may guide the design and application of these interesting alloys in future nuclear reactors and … Continue reading Amorphous and Refractory High Entropy Alloys
Novel high entropy ceramics for extreme environments
We investigate the radiation response of a hard refractory high entropy carbide (HEC): the (CrNbTaTiW)C. Comparison with the high entropy alloy (HEA) has shown the HEC outperforms the HEA under irradiation. Results suggest high-entropy ceramics can be alternative to HEAs in extreme environments. Available now at Acta Materialia (open access)! Do not forget to see … Continue reading Novel high entropy ceramics for extreme environments
Advancing the field of fine-grained aluminium alloys
In a new pre-print available at SSRN Electronic Journal, Samberger et al. introduce a new concept for fine-grained aluminium alloys. The authors shows a process of synthesis that resulted in a fine-grained aluminium crossover alloys intended to be applied in high-temperature forming processes. The use of EBSD unravels the active role of T-phase precipitates on … Continue reading Advancing the field of fine-grained aluminium alloys
