Using the Plasma FIB as a revolutionary tool for studying radiation effects in solids: cover page award!

~ Matheus A. Tunes ~ 4 Comments

Our recent work entitled "Rethinking radiation effects in materials science using the plasma-focused ion beam" published in the September issue of the historically prestigious Journal of Materials Science (Springer) has been awarded the cover page of the November 2022 issue (volume 57, number 41). A very nice editorial has been written by Professor C. Barry … Continue reading Using the Plasma FIB as a revolutionary tool for studying radiation effects in solids: cover page award!

Nanocrystalline lightweight alloys for space exploration

~ Matheus A. Tunes ~ Leave a comment

We continue in our saga aiming at finding better radiation-resistant materials for applications in the extreme environment of the solar system. I am delighted to introduce you our new paper that was led by Patrick Willenshofer (another genius from Montanuniversitaet Leoben). In this paper, we introduce a revolutionary nanocrystalline crossover aluminium alloy that scored the … Continue reading Nanocrystalline lightweight alloys for space exploration

Discovery of FeCo nanomagnets under irradiation in a high-entropy alloy

~ Matheus A. Tunes ~ 1 Comment

A modified version of the well-known Cantor's alloy, the nanocrystalline CoCrCuFeNi high-entropy alloy was subjected to heavy-ion irradiation in situ within a TEM in our most recent study within the field of potential new nuclear materials. The stability of the alloy was investigated in a broad range of irradiation doses and temperature, revealing the nucleation … Continue reading Discovery of FeCo nanomagnets under irradiation in a high-entropy alloy

MATLAB now fully integrated with SRIM!

~ Matheus A. Tunes ~ Leave a comment

We have completed -- once and for all -- a full integration of MATLAB with the SRIM code. Now the MATLAB code features the possibility to calculate displacement-per-atoms (DPA) in a wide variety of conditions and using all existing DPA methodologies (R.E. Stoller with quick-damage and Y. Zhang with full cascades). Calculations are performed in … Continue reading MATLAB now fully integrated with SRIM!

The interplay of H in degrading Zr and its alloys

~ Matheus A. Tunes ~ Leave a comment

In a recent talk, I address the problem of H in deteriorating severely the properties of the most important metal in nuclear industry, Zr, due to the formation of the Zr hydrides. A throughout good paper H effects in metals was recently written by Professor Milos Djukic, which I highly recommend reading. Abstract The decision … Continue reading The interplay of H in degrading Zr and its alloys

ACerS highlights Cr2AlC MAX Phases pathway to extreme environments

~ Matheus A. Tunes ~ 1 Comment

MAX radiation protection for next-generation nuclear power plants, by Jonathon Foreman, Ceramic Tech Today. "The radiation tolerance of MAX phases is of particular interest to researchers because it makes these materials ideal candidates for use in next-generation nuclear power technologies. Studies that exposed various MAX compositions to low and high doses of high-energy ions found … Continue reading ACerS highlights Cr2AlC MAX Phases pathway to extreme environments
