The effect of high-energy ball milling a mixture of Fe and h-BN with weight ratio of Fe:BN = 15, 4, 1, 0.36 on the phase composition and magnetic properties of the synthesized material has been investigated. Highenergy ball milling demonstrated a significant change in the phase content, structure, and magnetic characteristics upon MA and followed annealing at 600 0 C, in particular upon annealing, and the coercivity of the MA powder reached HC = 43 kA/m (540 Oe).
