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。

Internal friction peaks asscciated with the presence of carbon in several types of f.c.c. alloy-steel (18/8 type stainless steel and high manganese steel) have been observed from measurements with a torsion pendulum. The temperature for maximum internal friction lies between 200-300℃with a frequency of vibration of about I cycle per second. The height uf the peak rises and the position of the peak shifts to a lower temperature with an increase of the carbon content. When the amount of carbon in solid solution is reduced by tempering the specimen at an elevated temperature, the height of the peak lowers and the peak shifts to a higher temperature. A comparison of the activation energy and the diffusion ccefficients determined by internal friction methods with those measured in conventional macro-diffusion experiments reveals that the observed internal friction peak is associated with the stress-indused diffusion of carbon in these face-centered cubic steels.

用扭摆作内耗测量,发现了几种面心立方系合金钢(18/8型不锈钢及高锰钢)中含碳可以引起内耗峰。当振动频率约为每秒1周时,峰的巅值温度在200-300℃之间。当钢中固溶体的碳量增多时,内耗峰升高而峰的位置移向低温,当钢中所含的碳因回火而发生沉淀时,内耗峰降低而峰的位置移向高温。把内耗方法所测得的激活能、弛豫时间和由此计算所得的扩散系数与资料上所载的碳在面心立方系的钢中宏观扩散的数据相比较,指出所观测的内耗峰确是由于碳在钢中的微扩散所引起来的。 用同样的实验方法也发现了碳在镍铝合金及在纯镍中由于微扩散而引起的内耗峰。这些实验指出,碳在面心立方系晶体中微扩散而引起内耗峰这件事实,可能是一种普遍的现象。

Internal friction in hardened carbon steels was measured with a torsion pendulum and an internal friction peak was observed around 130℃when measurements were taken from room temperature upwards. This peak disappeared completely after the temperature of the specimen reached 170℃. This phenomenon was observed in carbon steels containing carbon ranging from 0.29% to 1.4%, and also in an alloy steel. The appearance of this internal friction peak seems to indicate that the transformation product ( ∈ -carbide)...

Internal friction in hardened carbon steels was measured with a torsion pendulum and an internal friction peak was observed around 130℃when measurements were taken from room temperature upwards. This peak disappeared completely after the temperature of the specimen reached 170℃. This phenomenon was observed in carbon steels containing carbon ranging from 0.29% to 1.4%, and also in an alloy steel. The appearance of this internal friction peak seems to indicate that the transformation product ( ∈ -carbide) formed in the first-stage tempering of martensite is in coherence with its parent phase, and the origin of internal friction is the stress-induced movement of the plane of coherence.

用扭摆测量淬硬碳钢的内耗,当测量温度由室温渐渐升高时,在130℃附近有一个内耗峰出现。当温度达到170℃后再降温测量,这个内耗峰完全消逝不见。上述的现象在含碳0.29%到1.4%的几种淬硬碳钢和淬硬滚珠钢中都曾经看到。由内耗峰的出现可以认为马氏体在第一个回火阶段中的转变产物(ε-碳化铁)与母体具有共格性,由于共格界面的应力感生运动而引起内耗。 曾用具有马氏体组织的0.25%碳钢试样作实验,没有观测到上述的内耗峰。但是当回火温度达到280-300℃以后,在降温或升温测量中都观测到一个内耗峰(在150℃附近)。这表示低碳马氏体在第三个回火阶段中的转变产物与母体具有共格性。但是由于这个内耗峰的表现与上述高碳试样的内耗峰不同,所以我们认为这转变产物并不是ε-碳化铁。
