The formation of σ-phase in a 18% Cr 11% Ni 2.6% Mo 0.8% Ti stainless steel has been investigated. Microscopic and X-ray examinations showed that the formationσf σ-phase from δ-ferrite was accompanied by the formation of austenite, the reaction being most rapid at 850℃

本文叙述在含钼、钛的18/8型不锈钢中σ-相形成的过程及其对钢的性能的影响。 金相及X线衍射分析证实:在复相铬镍不锈钢中,铁素体分解成σ-相以在850℃为最快。应用特殊的侵蚀剂及高倍的金相检查,发现σ-相的沉淀开始发生于铁素体相界;伴随着σ-相的形成,其周围铁素体重结晶为奥氏体。 由于σ-相的形成,钢的硬度增加,韧性显著降低,因而严重地影响了钢的安全使用,但是适当的热处理可以恢复其原来的组织及性能。

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。

The decomposition of δ-ferrite at 750°,850° and 950℃ in quenched 18/8/3/1Cr-Ni-Mo-Ti stainless steel specimens has been studied microscopically,thetransformation products being electrolytically extracted and identified by X-raydiffraction method.At early stages of decomposition accicular austenite forms along certaincrystallographic planes of δ-ferrite.As a result,the remaining ferrite becomesenriched in Cr,Mo and impoverished in C,Ni,Mn,and was found to transformsubsequently to sigma which begins after heating for 5-6 minutes at 850℃.Precipitation of titanium carbide first occurs in the ferrite grains,later itmakes appearance along the ferrite-austenite interphase boundaries and along thetwinning planes within the austenite grain.The precipitation of titanium carbideseems to have no appreciable effect on the sequence of decomposition of δ-ferrite.The impact value of the steel was found to decrease very markedly before thecommencement of the δ→σ transformation and it is considered that this mightbe associated with the titanium carbide precipitation.

应用金相法研究了18/8/3/1 Cr-Ni-Mo-Ti不锈钢经1300℃固溶处理后在950℃,850℃及750℃恒温分解初期金相组织的变化,并用电解分离及X射线衍射方法鉴定在不同恒温分解阶段δ-铁素体分解的产物。观察到由于提高了固溶处理温度,高温固定下来的铁素体极为不稳定,在分解为奥氏体的同时有TiC的沉淀出现。当δ→γ的转变,由于Cr,Mo等合金元素的偏聚不能继续进行时,才发现残留的δ-铁素体转变为σ-相。过去一般认为18/8型不锈钢在550—1000℃保温后,室温冲击靭性的降低是由于σ-相的沉淀所引起的,试验结果指出在σ-相出现之前,钢的冲击靭性已显著下降,这种现象可能与δ-铁素体分解初期TiC的沉淀有关。
