| Abstract Scope |
A combinatorial assessment of composition-microstructure-magnetic property relationships in a magnetic high entropy AlCoxCr1-xFeNi alloy (0≤x≤1) system has been carried out using compositionally graded alloys fabricated via laser additive manufacturing. At one end the AlCoFeNi composition (x=1) consisted of equiaxed B2 grains, at the other extreme, the AlCrFeNi composition (x=0) exhibited grains with pronounced spinodal decomposition, resulting in a B2+ bcc microstructure with the degree of phase separation (spinodal decomposition) progressively increasing with Cr content in these AlCoxCr1-xFeNi alloys. While the saturation magnetization (MS) monotonically increases six times from x=0 to x=1, the coercivity (HC) variation is non-monotonic, increasing seven times from x=0 to x=0.4, and subsequently decreasing fourteen times from x=0.4 to x=1.0. Such substantial changes in the magnetization behavior and properties of magnetic high entropy systems opens possibilities of tuning these alloys for specific soft or hard magnetic component applications, such as electrical machines in the energy industry. |
