Abstract

High magnetic field assisted heat treatment process was used to regulate the microstructure and properties of AlCoCrCuFeNi high-entropy alloy. Results show that applying magnetic field can refine the FeCoCr-rich phase and suppress the large regional segregation of Cu-rich phase. The strength of the alloy increases greatly from 1482 MPa to 1795 MPa and the elongation also increases from 23% to 27%. The saturation magnetization is depressed after the magnetic field is applied. These variations are attributed to the decrease of Cu-rich phase segregation, grain refinement, and also the slightly decreased volume fraction of BCC phase upon applying high magnetic field.
