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。

The microstructures of isothermal treatment of 18CrNiWA steel at various austenitizing temperatures were investigated by means of optical and electron microscopes. It is found that within the whole range of intermediate-temperature both massive ferrite and lath ferrite (i.e. bainite ferrite) can be formed. These morphologies are different from each other. It is shown that raising isothermal temperature or lowering austenitizing temperature would favour the formation of massive ferrite, while converse conditions would promote the formation of lath ferrite. The massive ferrite of intermediate-temperature transformation has some characteristics:(1)There is no surface relief.(2)The massive ferrite of which three-dimension appearance is equiaxed or irregular has its chunky substructures with higher density of dislocations.(3)It nucleates simultaneously both in in tragranularity and in grain boundaries.(4)It grows across the grain boundaries of parent phase or the twin, the trace of austenite boundary being preserved, but there is not any inheritance of twin structure.(5)In the massive ferrite formed at higher temperature, some island constituents are often enveloped by massive ferrite without the precipitation of carbides. The carbon concentration of the former is much higher than the initial average concentration in steel. In the massive ferrite formed at lower temperature, carbides precipitate with the morphology like Widmanstatten structure. The four characteristics of phase transformation mentioned above(1)-(4)are similar to those of massive transformation. It is newly considered that the r→a transformation of the short range diffusion of iron atoms accompanied by a long range diffusion of carbon atoms may result in the formation of massive ferrite of intermediate-temperature.

应用光学显微镜及电子显微镜对18 CrNiWA钢经不同温度奥氏体化及等温处理所得的组织进行了研究,发现该钢在整个中温转变温度范围内可同时存在块状铁素体及板条状铁素体(即贝氏体铁素体),这是两种不同类型的铁素体组织。提高等温温度或降低奥氏体化温度有利于块状铁素体形成;反之有利于贝氏体铁素体转变;并得出这种中温块状铁素体具有以下的相变特征:(1)无浮凸效应。(2)三维形态呈等抽状或不规则的外形,它是由高密度位错的块状亚结构所组成。(3)可同时在晶内和晶界形核。(4)能跨越原晶界或孪晶界而生长,并仍保留原奥氏体晶界的痕迹,但不继承孪晶组织。(5)形成温度较高时,得到无碳化物析出的块状铁素体包围着的岛状组织,后者含碳量远高于原始的平均成份;形成温度较低时,在块状铁素体中可析出单向或多向分布的碳化物。上述(1)~(4)四种相变特征与块状转变相类似。我们初步认为这种中温块状铁素体的形成是铁原子短程扩散的γ→α转变与碳原子长程扩散的综合结果。

The transformation of the massive ferrite, besides the lath one, was observed in the low or medium carbon ahoy steels under middle temperatures. The massive ferrite consiste of densely dislocated substructural chunks, which are equi-axial or irregular on three dimensional morphology. They nucleate and grow noncoherently either in the interior or along the boundary of grains. No definite orientation,namely neither habit plane nor growth orientation, was found during γ→a transformation. The carbides of different...

The transformation of the massive ferrite, besides the lath one, was observed in the low or medium carbon ahoy steels under middle temperatures. The massive ferrite consiste of densely dislocated substructural chunks, which are equi-axial or irregular on three dimensional morphology. They nucleate and grow noncoherently either in the interior or along the boundary of grains. No definite orientation,namely neither habit plane nor growth orientation, was found during γ→a transformation. The carbides of different arrangements which exist certain orientations and habit planes may be presented in the chunks with the decreasing growth temperature. Some island constituents rich in carbon which is composed of twinned martensite or martensite with retained austenite at room temperature may be also formed in or at the massive ferrite chunks or along the grain boundaries. The two above-mentioned orientations between the martensite and matrix are the relationship of K-S and N-W. It seems to be considered that the formation of middle temperature massive ferrite may be resulted by the γ→α transformation of a short range diffusion of Fe atoms accompanied with a long range diffusion in the way of island rich in carbon or carbide as well

在低、中碳合金钢的中温区内,除板条状铁素体转变外还存在块状铁素体转变。中温块状铁素体的三维形态呈不规则的或等轴的块状,系由较高密度位错的块状亚结构所组成,它可在晶内或晶界形核,非共格长大。在相变时,γ/α间不具有固定的位向关系、惯析面与长大取向。随着形成温度的降低,在块内可出现不同分布方式的碳化物,它们与基体间各具有一定的位向关系和惯析面。在块内、块间或沿晶界可形成富碳的岛状组织,常温下它是由M或M+A所组成,其中马氏体与母相间有K-S和N-W位向关系。初步认为,中温块状铁素体组织的形成是铁原子短程扩散的γ→α转变与碳原子长程扩散并以富碳岛状组织或碳化物的方式出现的综合结果。
