本文采用共振法、膨胀法研究了铁磁性恒弹性合金居里温度随时效温度的变化规律 ,并与用磁秤法测量的结果进行了比较。结果显示 ,共振法、膨胀法测得的居里温度值与磁秤法测得的居里温度值相近 ,同时它们获得的居里温度随时效温度的变化规律一致 ,从 4 0 0～ 6 0 0℃ ,居里温度随时效温的升高而减小 ;从 6 0 0～ 70 0℃ ,居里温度随时效温度的升高而升高
In this paper, the change law of Curie temperature of ferromagnetic constant elastic alloy with aging temperature was studied by resonance method and expansion method, and compared with the results measured by magnetic scale method. The results show that the Curie temperature measured by the resonance method and the dilatancy method are similar to the Curie temperature measured by the magnetic scale method, and the Curie temperature obtained by them is consistent with the aging temperature. From 400 to 600 Curie temperature decreases with the increase of aging temperature at 0 ℃. Curie temperature increases with the aging temperature from 600 ℃ to 70 ℃
