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

Key to recycling

~ Matheus A. Tunes ~ Leave a comment

From Montanuniversität Leoben: https://www.unileoben.ac.at/en/newsdetail/schluessel-zum-recycling For almost a century, commercial aluminum materials have been developed and optimized for high performance in specific applications within strict chemical confines of industrially established alloy classes. The requirements associated with sustainable lightweighting concepts call for new strategies that offer a broader property portfolio with a better trade-off between formability, achievable … Continue reading Key to recycling

High-entropy alloys are indeed radiation resistant. What about the high-entropy?

~ Matheus A. Tunes ~ Leave a comment

In another great collaboration with Oak Ridge National Laboratory and Universities of Huddersfield, Leoben and São Paulo, we have investigated in depth the radiation response of a FeCrMnNi high-entropy alloy (HEA) compared with a commercial austenitic stainless steel. Yes, the HEA outperforms the steel by a 80% margin when thermodynamic stability of the matrix phase … Continue reading High-entropy alloys are indeed radiation resistant. What about the high-entropy?
