本文研究了Ni为30～32％,Mn为1～3％其余为Fe的Fe-Ni-Mn热磁补偿合金。当调整Ni和Mn含量时, 在工作磁场为1600A/m,温度在293K(20℃) 可使磁感应强度B值的变化量在5×10~(-2)或8×10~(-2)T范围之内。
In this paper, the Fe-Ni-Mn thermo-magnetic compensation alloy with Ni of 30 ~ 32%, Mn of 1 ~ 3% and the balance of Fe was studied. When the content of Ni and Mn is adjusted, the change of B value of magnetic induction intensity is 5 × 10 -2 or 8 × 10 -2 at a working magnetic field of 1600 A / m and a temperature of 293 K (20 ℃) T range.
