The approach to magentic saturation in the cases of iron, nickel, and a number of iron-cobalt alloys at various temperatures has been studied in the range of field from a few hundred to 6,000 oersteds. It has been found that for annealed and moderately cold-worked specimens the differential susceptibility can be represented fairly accurately by a formula of the form

本工作依据微分磁化率的观测,以研究铁、镍、和几种铁钴合金在室温和高温下的“趋近饱和”现象。由实验结果得知,在数百到6000奥斯特的磁场下 微分磁化率和磁场强度的关系可用下式表出: (I/H)_T=A/H~2+2B/H~3+C/H~(1/2)+D,式中I表磁化强度,H表磁场强度,T表温度。在室温附近,式中末两项比前两项小得多,所以末两项的总值可以约略用一常数来代替;但在高温下就不然了。如果将一曾经驯炼的试品逐步加以冷作 则系数A和B最初跟冷作程度作跳跃式的增加;但对于经过剧烈冷作的试品上式就不适用。在驯炼状态下,A和B跟温度的上升而减小;到消失时温度还相当低于居里点。因本实验中所得数据的准确度不够所以不能依据它们来确定D的值;但如果将D略去而计算系数C的值,则可以确定到九成。C的数量级和它跟温度变化的情形大致是和Holstein和Primakoff的理论相符的 系数B和“磁晶各向异性”系数K的平方成正比;但用B的实验值和B的理论式比较而算得的K_1则和从单晶体观测所得的K_1只有数量级的符合。

A detailed thermomagnetic analysis was carried out on a number of alloys along a tie-line in the two-phase (β+β') region of the Fe-Ni-Al ternary system. The supersaturated solid solution, obtained by quenching an alloy close to the composition Fe2NiAl, broke up very fast at relatively high temperatures ( ~ 850℃), precipitation being completed in a little more than a minute. The β' phase formed at 850℃ still contained about 35 at. % iron, with a Curie point near 400℃. When this alloy, after going through such...

A detailed thermomagnetic analysis was carried out on a number of alloys along a tie-line in the two-phase (β+β') region of the Fe-Ni-Al ternary system. The supersaturated solid solution, obtained by quenching an alloy close to the composition Fe2NiAl, broke up very fast at relatively high temperatures ( ~ 850℃), precipitation being completed in a little more than a minute. The β' phase formed at 850℃ still contained about 35 at. % iron, with a Curie point near 400℃. When this alloy, after going through such a short tempering at 850℃ followed by quenching, was heated up to 600-700℃ again, the β' phase formed during the first tempering continued to decompose rapidly, losing enough iron to become nonmagnetic in not much more than ten minutes. This caused the room-temperature coercive force of the alloy to rise to about 500 Oe. Such a phenomenon is in agreement with БгЛнвиЦ'S. г. suggestion of "post-precipitation". The magnetic measurements showed, moreover, that the post-precipitatioa of the β' phase was "reversible", that is, when the alloy was brought up to 850℃ again after quenching from the second tempering at 600-700℃, theβ' phase could recover its equilibrium composition for 850℃ in a few minutes. Decomposition of the supersaturated solid solution FejNiAl at relatively low temperatures (below 700℃) was quite slow, and, furthermore, there was considerable evidence that the process was "non-uniform". On the basis of the above findings, the fact that high coercive force in the alloy FeaNiAl cannot be obtained by quenching from above the solution temperature plus tempering at relatively low temperatures (600-700℃) is interpreted in the light of the single-domain particle theory.

用热磁分析方法较仔细地观测了Fe-Ni-Al三元系合金沿β+β′两相区内某一结线上的几个不同成分的合金样品。淬火所得的成分接近Fe_2NiAl的过饱和固溶体在较高温度(~850℃)分解甚快,在一分钟内脱溶基本上完成。在850℃分出的β′相还含铁约35at.%,其居里点在400℃附近。在850℃经短时间回火继以水淬的合金,在600—700℃再经适当的回火,则首次回火所生成的β′相继续迅速分解,在不超过十分钟内损失大量的铁而变成非铁磁性的;其在室温的H_c可增到500奥斯特。这和Б.Г.Лившнц“所提出的继续脱溶”的假设相符。磁性观测的结果证明:β′相的继续脱溶是“可逆的”,就是说,把曾在600—700℃回火的合金重热至850℃时β′相能在几分钟内恢复850℃的平衡成分。Fe_2NiAl过饱和固溶体在较低温度(70O℃以下)分解极慢,并且其过程是明显地“不均匀”的。因此,这种合金不能通过高温淬火继以较低温度(600—700℃)回火的处理来获得高H_c的事实可以用单畴粒子的理论加以解释。

Small quantities (0.1, 0.5 and 1.0 weight percent) of rare earth oxides (La2O3, CeO2, Sm2O3, Gd2O3) and Y2O3 were added to a square-loop Mg-Mn ferrite which contained some ZnO and CuO. The effect of these additions on the static hysteresis loop and the signal to noise ratio was investigated. The samples were prepared by the usual oxide method, sintered 2 hours in air at 1300℃ and quenched from l050℃ or 950℃. Preli-

本文报导了少量稀土元素氧化物(La_2O_3,CeO_2,Sm_2O_3,Gd_2O_3和Y_2O_3)对于一种含ZnO和CuO的Mg-Mn矩磁铁氧体磁心性能的影响,简要地叙述了样品的制备过程。测量了磁心的静态磁滞迴线,饱和磁化强度,居里点和讯号杂音比。实验结果表明:加La_2O_3或Gd_2O_3可以增加矩形比和B-Hm/2/B_m和讯号杂音比,并使后者的分布往高比值移动,但加CeO_2,Sm_2O_3或Y_2O_3却没有使这些性能改善,甚至有所降低。文中举例说明了磁心尺寸对于矩形比、淬火温度和稀土元素氧化物的含量对于讯号杂音比的影响。最后指出:这种方法可能提供一种改善磁心某些性能而不显著改变其居里点的途径。
