时效温度对埃林瓦合金负ΔE效应影响

Influence of Ageing Temperature on the Negative △E Effect of Elinvar Alloy

研究了时效温度对直流磁场作用下Fe-Ni-Cr-Ti弥散硬化埃林瓦合金负△E效应和内耗Q^(-1)影响。用γ相析出及对畴壁钉扎效应对其规律进行了解释。

The influence of ageing temperature of the negative AE effect and internal friction Q-1 of dispersion-hardened Elinvar alloy Fe-Ni-Cr-Ti under the action of a DC magnetic field was studied. The results are discussed for its behavior by way of γ' -phase precipitation and nailing-down effect on domain wall.
