Magnetic properties of the complex concentrated alloy system CoFeNi(0.5)Cr(0.5)Al(x)

We study the change in magnetisation with paramagnetic Al addition in the CoFeNi(0.5)Cr(0.5)–Al(x) (x: 0, 0.5, 1, and 1.5) complex concentrated alloy. The compositions were developed utilising the Mulliken electronegativity and d-electron/atom ratio. Spherical FeCr rich nanoprecipitates are observed...

description We study the change in magnetisation with paramagnetic Al addition in the CoFeNi(0.5)Cr(0.5)–Al(x) (x: 0, 0.5, 1, and 1.5) complex concentrated alloy. The compositions were developed utilising the Mulliken electronegativity and d-electron/atom ratio. Spherical FeCr rich nanoprecipitates are observed for X: 1.0 and 1.5 in an AlCoNi-rich matrix. A ~ 5 × increase in magnetisation (from 22 to 96 Am(2)/kg) coincides with this nanoprecipitate formation—the main magnetic contribution is determined to be from FeCr nanoprecipitates. The magnetisation increase is strange as paramagnetic Al addition dilutes the ferromagnetic Fe/Co/Ni additions. In this paper we discuss the magnetic and structural characterisation of the CoFeNi(0.5)Cr(0.5)–Al(x) composition and attempt to relate it to the interfacial energy.
