本文对一些铁磁性和反铁磁性合金中的恒弹性模量特性的起源作了评述。引起反常弹性模量(△E)的各种因素均来自磁有序化。详细研究了铁-镍系中的各种影响因素:诸如第三合金元素,沉淀硬化过程,冷加工和成品热处理。在高达300A/cm的直流磁场中研究了一种技术恒弹性合金在各种振动模式的弹性能。在f>30千赫时检测了趋肤效应的影响。叙述了某些动态应用(即机电滤波器,频率标准,延迟线)。
This article reviews the origin of the constant modulus of elasticity in some ferromagnetic and antiferromagnetic alloys. Various factors that cause anomalous elastic modulus (ΔE) are derived from magnetic ordering. Various factors in the iron-nickel system have been studied in detail: such as the third alloying element, precipitation hardening process, cold working and finished product heat treatment. In a DC magnetic field of up to 300 A / cm, we have studied the elastic properties of a technique for constant elastic alloys in various vibration modes. The effect of the skin effect was tested at f> 30 kHz. Describes some of the dynamic applications (ie electromechanical filters, frequency standards, delay lines).
