Microstructure and properties of AlCoCrCuFeNi high-entropy alloy solidified under high magnetic field

High static magnetic field was used to regulate the microstructure and properties of AlCoCrCuFeNi high entropy alloy. Result shows that applying high magnetic field does not change the microstructure obviously but can improve the content of ferromagnetic FeCr-rich BCC phase. The yield stress and plastic strain were improved simultaneously, and saturation magnetization value increased from 27.3 emu/g to 34.5 emu/g. Our research shows that introducing high magnetic field is a good method to tailor the mechanical and magnetic properties of high-entropy alloys. (c) 2020 Elsevier B.V. All rights reserved.

Automated summary

The study demonstrates that using a high static magnetic field can improve the properties of AlCoCrCuFeNi high entropy alloy, especially the content of ferromagnetic FeCr-rich BCC phase. Introducing a high magnetic field not only enhances the yield stress and plastic strain, but also increases the saturation magnetization value.
