M.S.O.整磁合金（Fe-Ni-Cr系）の特性に及ぼす加工の影響

抄録

The change of the characteristics of the MSO magnetic shunt alloys by cold working up to 90% and successive annealing was measured. With increasing the degree of cold working, the permeability at 0°, μ₀, decreases, and the temperature coefficient of the permeability, α, increases and the temperature coefficient of the permeability, α, increases and the temperature interval with same temperature coefficient of the permeability, ΔT₀, decreases. By annealing, those properties are recovered and, above 600°, their values become to as almost the same as those before cold working. The differences of permeability between the states as cold work and after annealing are not similar each other, but having a maximum value for permeability of the latter state. Further, the change of saturation, magnetization I_s, coercive force, H_c, electrical resistance, ΔR⁄R, and Rockwell hardness, RH, by annealing was also measured.
