Fe-N amorphous alloy and ε- FexN alloy were prepared by mechanical ball milling with Fe and solid hexagonal boron nitride (h-BN) as nitrogen resource. The microstructural and magnetic transforming rules of different volume ratios of mixtures of Fe and h-BN (1:12.5, 1:5.4, 1:1.2, and 1:0.38) was studied under different ball-to-powder weight ratios. phase transition and magnetism were characterized with X-ray diffraction and vibrating sample magnetometer (VSM). According to the results, samples of the first three volume ratios have similar phase transition rules in different ball-to-powder weight ratios, and the sample with smaller ball-to-powder weight ratio costs more time in alloy formation. The changing rules and mechanisms of coercivity of four ratio samples with the extension of ball milling time has been clarified. |
