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

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

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?
