一、实验目的我国仪器仪表工业的发展,要求提供矫顽力(Hc)在0.0035奥斯特以下的低矫顽合金带。带厚0.35～0.50毫米。同时还要求合金具有尽可能低的剩磁感应(Br)和尽可能高的导磁率(μ)。为使合金具有好的磁性能对环境温度的稳定性,合金的居里点Ao需远高于环境温度。早在1951年R.M.Bozorth就曾报导当时发明的所谓“超坡莫合金”获得了超过上述要求的性能。即达到:矫顽力 Hc=0.002奥斯特;初始导磁
First, the purpose of the experiment Instrumentation industry in China, the development of the provision of coercivity (Hc) 0.0035 Oersted below the low coercive zone. With a thickness of 0.35 ~ 0.50 mm. At the same time, it is also required that the alloy has the lowest remanence (Br) and the highest possible permeability (μ). In order to make the alloy have good magnetic properties of the stability of the ambient temperature, the Curie point Ao of the alloy is much higher than the ambient temperature. As early as 1951, R.M. Bozorth reported that the so-called “permalloy” invented at that time obtained performance exceeding the above requirements. That is: Coercive force Hc = 0.002 Oersted; initial permeability
