PURPOSE:To offer a magnetic alloy composed of a single alloy, having a complex magnetic property and excellent in workability by preparing an alloy containing specified rates of Cr, Co, Si, V, Nb, Ta and Fe. CONSTITUTION:An alloy comprising, by weight ratio, 17-35% Cr, 8-20% Co, 0.1-5% Si, 0.1-10% of one or more of V, Nb and Ta, and the balance being Fe, is prepared. The alloy may contain 0.1-10% of on more of Mn, Y, Cu, Zn, Al, C, rare metals, Ru, Rh, Pd, Os, Ir and Pt as additional components. Its complex magnetic property is obtained by solution-treating the alloy in an alpha+gamma dual phase zone and utilizing the spinodal decomposition of each phase, a gamma alpha' transition mechanism and an age-precipitation-hardening mechanism so that mainly alpha contributes to a large coercive force while gamma contributes to a small coerive force. Thus, the magnetic alloy having mass-producibility is produced at a low cost. |
