It is well-known that blue brittleness and temper brittleness of steel are related to diffusion and precipitation in steel. An attempt was made in the present research to investigate this problem by means of internal friction measurements. Experiments show that the diffusion of carbon in α-iron is not affected by carbon concentration, alloying elements and the stage of precipitation in iron. The diffusion of nitrogen in α-iron is, however, hindered by the addition of alloying elements, and is enhanced...

一般认为钢的变脆例如蓝脆和回火脆都与钢中的扩散和沉淀有关系。本文尝试用内耗测量的方法研究碳与氮在α-铁及碳素钢中的扩散、脱溶和沉淀,从而进一步地了解钢的变脆的机构。实验的结果指出,碳在α-铁中的扩散不受自身浓度、合金元素和沉淀历史的影响。氮的情形与碳显著不同,合金元素使氮的扩散变慢,在沉淀初期使氮的扩散加速。 较有系统地研究了碳、氮在加工后的α-铁中脱溶时所引起的内耗峰(当振动频率约为每秒1周时出现在250℃左右),发现了高温淬火在含碳或氮较多的试样中所产生的内应力也可以引起这个内耗峰。实验指出:①这个脱溶内耗峰的出现条件与钢的蓝脆的出现条件相同,都是一种应变时效或淬火时效的现象;②与这个内耗峰有关的碳、氮是处于原子的状态。这些联系使我们认为钢的蓝脆是一种应变脱溶或淬火脱溶的过程,是由于原子状态的碳或氮聚集于钢中的内应力区域或晶体缺陷(例如原子脱节)中所引起来的。关于这方面的深入研究正在继续进行中。 根据本实验及以前关于钢铁中碳氮的扩散、脱溶和沉淀所得的结果,对于钢的回火脆的机构也提出了一种初步的看法。回火脆是一种回火沉淀的过程,引起回火脆的沉淀似乎是氮化物而不是碳化物。

In the spectrochemical analysis of high speed steels with a small current activated a.c. arc (after Aбрамсон), the results of analysis were found to be affected by different previous heat-treatments given to the steel samples. To study this effect we selected 10 chromium steel samples of different carbon content. Spectrochemical analysis of these samples under different procedures of heat treatment shows that with an a.c. arc (5 amp.) the results of analysis of Cr for annealed and for hardened samples of the same steel are different and the difference increases with the increase of carbon content. We are inclined to think that in a low energy light source, the evaporation and the excitation of the alloying elements vary according to the existing form of carbon and this directly affects the results of spectrochemical analysis. The magnitude of this effect is different for different alloying elements, it is considerable in the case of Cr but is inappreciable in the case of Mn and Si.

我们用爱氏光源(低电流交流电弧)作高速钢的光谱分析时,发现样品的组织结构对于分析结果有影响。为了对这个现象得到进一步的了解,我们选择了10种含碳量不同的铬钢进行热处理试验和光谱分析。一系列实验的结果指出,用小电流(5安)电弧光源时,铬的光谱分析结果由于试样是退火组织或淬火组织而有差别,这个差别又随着钢中含碳量的增加而增加。我们认为,这种影响是由于碳在试样中存在状态的不同所引起的。在低功率光源中,这种不同使合金元素被蒸发和被激发的情况有所差别,因而就影响了光谱分析的结果。这种影响由于合金元素之不同而有程度上的不同,对铬的影响很显著,对锰和矽的影响则很小。此外,所选择的分析线对是弧线还是火花线,对于这种组织结构的效应也有显著的影响。 曾经进行了一些消除组织结构影响的实验。发现在应用低功率光源时,增加预燃时间并不能消除这个效应。用火花光源或大电流(8安)电弧光源时,这种影响大为减小。

Further study of the effect of micro-structure of the sample electrode on the spectrochemical analysis of steels revealed that the effect on the analysis of W, Si and Ni all increases with the increase of the carbon content and for different analysis line pairs chosen, the effect not only differs in magnitude but also can be different in direction as was observed in the case of Cr in chromium steels. The effect on the analysis of Mn in all the steel samples studied is not significant. Structure effects observed...

Further study of the effect of micro-structure of the sample electrode on the spectrochemical analysis of steels revealed that the effect on the analysis of W, Si and Ni all increases with the increase of the carbon content and for different analysis line pairs chosen, the effect not only differs in magnitude but also can be different in direction as was observed in the case of Cr in chromium steels. The effect on the analysis of Mn in all the steel samples studied is not significant. Structure effects observed under different excitation conditions show that under the same excitation condition, the arc temperature which is indicated by the log intensity ratio of two iron lines of different excitation potential is higher when the sample electrode is of annealed structure; and in light sources of the same arc temperature the relative concentration of alloying elements to iron is higher when the sample electrode is of quenched structure. Since these two factors have opposite effect on spectral line intensities, the result of analysis will be different for different line pairs chosen. If the analysis line pair is homologous, the effect observed is due to a difference of relative concentration of different elements in the arc column alone, and the result of analysis is always higher when the sample electrode is of quenched structure. This may he explained by the fact that the presence of carbon in solid solutions decreases the interatomic forces or shows a lowering of energy of volatilization. This lowering is different for different elements but all increases with the increase of carbon content.

在过去工作的基础上,进一步观察了合金钢的组织结构对于钨、镍、硅、锰的光谱分析的影响和碳钢的组织结构对于硅、锰的影响。这些影响都是随着钢中含碳量的增加而增加,对与不同元素有程度上的不同。改变激发条件的试验结果指出:1)在同一激发条件下,淬火组织试样的弧温比退火组织的低;2)在同一弧温时,弧柱中合金元素与铁元素的浓度比值是淬火组织的比退火组织的高。由于这两个因素对于谱线强度所发生的影响的方向相反,所以在实际的光谱分析中,组织结构的影响便有不同的表现。 根据分析线对中的分析线与内标线的激发能差值的大小,可以说明为什么采用离子线或原子线作分析线对时所观察到的组织结构影响不同或者方向相反。当所用的分析线对比较均称时,淬火组织试样的分析结果总是比退火的高。引起组织结构影响的主要原因是由于在不同组织结构时蒸发情况的不同。试样中所含溶解碳量的增加使原子间力相应地减小,这可以解释为什么含碳量不同以及不同的合金元素引起不同的组织结构影响。
