Studies on magnetic properties and ball-milling process of Fe-Si-Cr powders

FeSiCr ternary alloy, as an electromagnetic wave absorbing material, have received much scientific and technological attention in Military and Civilian application domains. For the fundamental scientific research, compositional studies have been conducted for FeSiCr ternary alloy, e .g . Fe_80-xSi₂₀Cr_x (0≤x≤20), Fe₇₅Si₁₅Cr₁₀, Fe₈₀Si₁₀Cr₁₀, Fe₈₀Si₂₀Cr₁₀, prepared by melt spinning. But studies about Si content in FeSiCr ternary alloy have not been conducted. In this work, the microstructure and magnetic properties of Fe_85.4-xSi_13+xCr_1.6(x=0,2,4,6) flake-shaped powders and milling time of Fe_81.4Si₁₇Cr_1.6 flake-shaped powders were investigated.
