    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。

    Two movable photo-multiplier tubes are set in the position of the plate holder of a medium quartz spectrograph. The photo-current of each is amplified by an AC amplifier, and, after rectification, is used to charge a condenser. A thyratron is connected parallel to the condenser for the internal standard line (Al 2660A). At a present value of the voltage of this condenser, the thyratron operates so as to switch off the reading instrument which is connected with the other condenser for the analysis line (Cu 2247 A). The final reading on the meter is proved to be proportional to the ratio of intensities of the two spectral lines.

    Internal friction in two kinds of iron-manganese alloy which contain Mn 17.5% and Mn 12.8% respectively and one kind of copper-aluminum alloy containing 13% Al were measured with a torsion pendulum, and internal friction peaks were observed in the temperature range in which the martensite or reverse martensite transformation is taken place. The condition for the appearance of this internal friction peak is that it occurs only when accompanied by the process of martensite-type transformation.

    用扭摆测量两种跌锰合金(Mn17.5%和12.8%)和一种铜铝合金(Al13%)的内耗,在发生正和反的马氏体相变的温度范围内各出现一个内耗峰。这种内耗峰出现的条件是必须伴随着马氏体式相变过程的进行。 用含Mn17.5%的铁锰合金作了系统实验,观察到内耗峰的高度随升温(或降温)速度和应力的增加而增高,随振动频率和含碳量的增加而减低。可以用振动一周内试样中转变量愈多内耗也愈大的关系得到统一的解释。 讨论了关于产生内耗峰的机构。认为主要由于马氏体相变是突然间完成,此时扭转的外力可视为常数,从应力和不均匀物质交互作用能的计算,可以证明外力所做的功必须损失一半,因而引起内耗。此外应力感生相变也可以引起很小一部分内耗。
