Effects of minor B addition on microstructure and properties of Al19Co20Fe20Ni41 eutectic high-entropy alloy

The simultaneous strengthening of mechanical and magnetic properties is an ideal fabrication strategy for soft-magnetic materials. A non-equiatomic Al19Co20Fe20Ni41 eutectic high-entropy alloy was prepared to investigate the alloying effect of B on the microstructure evolution, phase formation, mechanical and soft-magnetic properties. With the increase in B content, the microstructures of (Al19Co20Fe20Ni41)100−xBx alloys transformed from the...
