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.
