| 摘 要： | 对两类合金,即Ni-Fe-Nb和Ni-Fe-Nb-Al合金的热处理和磁性进行了实验。Ni-Fe-Nb合金经高温处理后与工业常用的钼坡莫合金同样具有较高的起始磁导率和最大磁导率。我们对Ni-Fe-Nb和4钼坡莫合金的物理参数进行了比较。Ni-Fe-Nb-Al合金有较高的硬度和电阻率。经过两次联合处理,可以达到较为适用的磁导率值。Ni-Fe-Nb-Al合金经高温缓慢冷却发生了调幅结构,调幅结构的周期约50单胞(数)或160埃。Ni-Fe-Nb-Al合金经970℃加热后快速冷却可以抑制调幅结构。具有调幅结构的材料硬度较高,矫顽力也略为增高。关键词：

| Abstract: | The magnetic properties of two kinds of alloys (Ni-Pe-Nb and Ni-Pe-Nb-Al) after various heat-treatments are studied. The initial and maximum permeabilities are high and can be compared with those of the technical Mo-permalloys. Some of the physical parameters of Ni-Pe-Nb and 4Mo-permalloy are tabulated here for comparison.The quaternary Ni-Pe-Nb-Al alloy possesses higher Vickers hardness and electrical resistivity. Curves of a. c. magnetic permeabilities of the Ni-Pe-Nb-Al alloy specimens are presented.In the specimens of Ni-Pe-Nb-Al after slow cooling from high temperature, modulated structures are developed with a wave-length of about 160?. Eapid cooling from 970℃ suppresses the formation of the modulated structure. The material with a modulated structure possesses higher hardness as well as higher coercive force.
