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。

Impact tests have been carried out on nodular cast iron in -the cast and forged conditions from -85℃ to 1070℃. The results indicate that nodular cast iron of predominantly ferritic matrix possesses two brittle temperature ranges (below 20℃ and between 550 and 700℃), and one comparatively more ductile range (between 850℃ and 1050℃).

Creep under very small torsional stress has been investigated for 99.95% polycrystalline iron in the temperature range of 350°-525℃. The general features of the creep curves obtained are essentially the same as those previously reported for 99.991% aluminum. The creep is shown to be consisted of two parts, one occurring at lower temperatures or shorter times and the other at higher temperatures or longer times. The first part of the creep is limited in extent and is associated with the viscous behavior of grain...

Creep under very small torsional stress has been investigated for 99.95% polycrystalline iron in the temperature range of 350°-525℃. The general features of the creep curves obtained are essentially the same as those previously reported for 99.991% aluminum. The creep is shown to be consisted of two parts, one occurring at lower temperatures or shorter times and the other at higher temperatures or longer times. The first part of the creep is limited in extent and is associated with the viscous behavior of grain boundaries. The activation energy for this grain-boundary creep is 78,000 ± 4,000 calories per mole according to the present creep and stress relaxation measurements. This value is close to the activation energy for self-diffusion of iron, a correlation which indicates that, in so far as to the mechanism of atomic migration is concerned, grain boundaries may not be very different from the interior of the grains.

用99.95%的多晶纯铁作了从350°-525℃的扭转微蠕变及应力弛豫试验,所得结果的概貌与以前用多晶纯铝所得的基本上相同。从蠕变曲线上可以看出这蠕变是由两部分组成的:第一部分是在较低温度或较短时间内发生的,第二部分是在较高温度或较长时间内发生的。第一部分的蠕变是有限的,是由于晶粒间界的粘滞性滑移所引起。根据微蠕变及应力弛豫测量的结果,这一部分蠕变所包含的激活能是78,000±4,000卡/克分子。这个激活能(晶粒间界滑移激活能)的数值与纯铁自扩散的激活能很相近,表示晶粒间界与晶粒内部对于原子迁移的基本过程而言并没有显著的差异。 加碳于纯铁中对于这两部分的蠕变都有显著的影响。最值得注意的结果是含碳量少到0.0004%时已经使晶粒间界的粘滞性滑移受到显著的阻碍。这些发现在控制金属高温蠕变的问题上指出一个一般性的原则,对于以前所提出来的晶粒间界空穴模型也提供了一些新的实验证据。 根据加碳的实验结果,对于第二部分高温蠕变的机构也提出了一个初步的看法,这蠕变所包括的基本过程可能是晶粒内部的空穴中的原子重新排列。
