Abstract
In this work, a high-entropy alloy Fe<sup>x</sup>Co<sup>6</sup>Al<sup>3</sup>Ni<sup>2</sup>Si (where x = 5, 6, 8) was obtained by mechanical alloying. The microstructure, phase and granulometric compositions of the obtained powders were studied. The required specific energy dose for the formation of a homogeneous solid solution (D = 30 W⋅h/g) was determined. Using the CALPHAD method, a phase diagram was constructed for the multicomponent Fe<sup>x</sup>Co<sup>6</sup>Al<sup>3</sup>Ni<sup>2</sup>Si system. The Fe8Co6Al3Ni2Si alloy powder after mechanical alloying showed a saturation magnetization of 154 emu/g and a coercive force of 53 Oe. Compact samples were obtained from the Fe<sup>x</sup>Co<sup>6</sup>Al<sup>3</sup>Ni<sup>2</sup>Si alloy powder in a spark plasma sintering installation and annealed at temperatures of 900, 950 and 1000°C. The microstructure and phase composition of the samples after annealing were studied. Tests of magnetic properties of samples showed that the saturation magnetization of samples ranged from 159 to 168 emu/g, coercive force – from 8.9 to 29.2 Oe. Compressive strength of samples ranged from 2190 to 2680 MPa, and microhardness – from 681 to 811 HV.
