The influence of austenitising temperature upon hardenability was determined

奥氏体化温度对硼钢淬透性的影响,从实验结果得到,在各种热处理条件下均随温度的提高逐渐降低。氧化及氮化的因素对硼钢淬透性的下降是有一定的影响,但硼原子本身在奥氏体中的分布情况对淬透性的影响是更重要的一个因素。在渗硼试样中观察硼化合物的形成,指出,从高奥氏体化温度直接淬火后,硼的沉淀物是在奥氏体晶界上及晶粒内均匀分布的,但在等温处理、正火处理或慢冷试样中,硼化合物大部份沉淀在奥氏体晶界上。因此,硼钢在高温奥氏体化后失去良好淬透性的原因,可能是由于硼原子从奥氏体晶界上的回扩散作用,使晶界上得不到足够的硼原子降低晶界能,引起硼的效能暂时的消失。

The relation between the Stability of β-C_2S and. the burning temperature has been inveatigated by means of X-ray,polorized microscope and TDA.The experimental results show that β-C_2 is a metastable modification, which tends to invert into γ-C_2S during cooling. From the samples burned in different temperatures varying from 950℃ to 1400℃, the relative content of γ-C_2S increases with lowering temperature. Dusting occurs even from samples burned at temperature of 1200℃ for 6 hours, but there is no dusting occured when the samples are burned twice at the same temperature with tempering only 5 hours in total,yet,the final product is always the mixture of β-C_2S and γ-C_2S.The afore-mentioned results apparently are different from the views of Yannaquis, who confirmed that: "β-C_2S obtained from burning temperatures between 950℃ and 1200℃ was stable at any temperature even under slow cooling."Depending on the characteristics of metastable β-C_2S, we use K_2O, Na_2O, MgO, Fe_2O_3,copper-slag and fluorspar as stabilizers to prevent the dusting from portland cement clinker.The experimental data thus obtained are believed of value to the practical control of raw mix at cement factories.

本文采用了X—射线分析、差热分析和显微镜观察,研究了β—C_2S的稳定性与烧成温度的关系。试验结果指出:β—C_2S是介稳的晶型,在冷却过程中要转换为γ—C_2S。从950℃~1400℃之间不同烧成温度的试样得知,烧成温度愈低,γ—C_2S的相对含量愈高。如果在1200℃经过两次煅烧,并经两次保温共达5小时,就能防止粉化现象。然而最终的产物为β-和γ—C_2S的混合物。据本试验结果,对Yannaquis所提出的“在950°~1200℃烧成的β—C_2S,在任何温度下都是稳定的晶型,甚至慢冷也是稳定的。”这一观点提出不同看法。 根据β—C_2S介稳定性的特征,试验了K_2O、Na_2O、MgO、Fe_2O_3、铜矿渣及螢石对防止普通水泥熟料粉化的作用,这对在生产实际中控制配科参数有一定的参考价值。

Many investigators have studied the embrittlement due to slow cooling in high temperature range in 18Ni maraging steel. It is generally believed that the embrittlement is related to the precipitation of TiC and Ti(C,N) on prior austenite grain boundaries. We have systematically investigated the regularities, behavior and causes of the embrittlement and got the results different from the ones obtained by the predecessors. The main results are as follows: after high-temperature annealing (1200℃ 1hr) and in intermediate isothermal holding at the most sensitive temperature (950℃), lots of M_3B_2 tates that cause the embrittlement of the steel Moreover, ways to control and to eliminate the embrit tlement are also searched.
