FIELD: metallurgy.SUBSTANCE: invention covers the alloys FeBSiPCCu, where 79?a?86 at.%, 5?b?13 at.%, 0<c?8 at.%, 1?x?8 at.%, 0?y?5 at.%, 0.4?z?1,4 at.% and 0.08?z/x?0.8, and FeBSiPCCu, where 81?a?86 at.%, 6?b?10 at.%, 2?c?8 at.%, 2?x?5 at.%, 0?y?4 at.%, 0.4?z?1.4 at.% and 0.08?z/x?0.8. Proposed method comprises producing the alloy to be heat treated under condition that temperature rise rate makes 100°C or more per minute and that process temperature is not lower than that the alloy crystallisation start.EFFECT: alloy permeability of 10000 or more and magnetic induction saturation of 1,65 Tl or more.14 cl, 4 dwg, 21 tbl, 74 ex |
