The decomposition of δ-ferrite between 550°—900℃ in quenched 18/8 stainless

金相方法研究了含少量钼、钛18/8 Cr-Ni不锈钢中δ-铁素体在900°—550℃恒温分解的过程。观察到在分解产物中没有σ-相。δ-铁素体分解形态及其机构随分解温度而有所不同。当分解温度高于750℃时,先析出奥氏体γ′,继之在未转变的铁素体中,才沉淀出碳化物。分解温度低于650℃时,则先析出碳化物,随后才出现有奥氏体γ′。介乎750°—650℃之间,δ-铁素体通过共析转变方式分解为碳化物及γ′。共析分解未能进行到底,在残留的铁素体中,有奥氏体γ′析出,由于合金元素分配的关系,δ→γ′的转变不久亦停止。在试验过程中,观察到电解磨光后,在碳化物未全部溶解或δ-铁素体已发生分解的样品表面上,出现有马氏体。用同佯手续制备1300℃固溶处理(碳化物全部溶解)的样品,则没有出现马氏体。初步认为马氏体的出现是由于电解磨光过程中产生自由表面所引起的。但是这种表面马氏体的形成似亦与奥氏体的含碳量有关,其形成机构尚待进一步的研究。

In this paper the authors study the change of various kinds of non-metallic inclusions in ball-bearing steel (G Cr 15) after remelting in the consutrode vacuum arc furnace, and the influence of chief technological factors, such as density of current, pressure, ratio of cross section of consutrode and mold etc. A laboratory vacuum arc consutrode furnace of 2.5 kg is used for remelting. Analysis of inclusions is done by the metallgraphic method. In order to explain the character of change of inclusions after...

In this paper the authors study the change of various kinds of non-metallic inclusions in ball-bearing steel (G Cr 15) after remelting in the consutrode vacuum arc furnace, and the influence of chief technological factors, such as density of current, pressure, ratio of cross section of consutrode and mold etc. A laboratory vacuum arc consutrode furnace of 2.5 kg is used for remelting. Analysis of inclusions is done by the metallgraphic method. In order to explain the character of change of inclusions after remelting the distribution of inclusions and depth of the bath in the ingot are also measured. On the basis of experiments the authors try to discuss and analyse the mechanism of reduction of inclusions in the ball-bearing steel after remelting.

本文研究了滚珠钢(滚铬15)在真空电弧炉重播前后各类非金属夹杂物含量的变化及电流密度、真空度、电极与坩锅截面比等主要工艺因素的影响。熔炼试验是在实验室2.5公斤真空电弧炉设备上进行的,夹杂物分析采用金相方法。为了进一步研究在重熔后钢中夹杂物的变化规律,也对钢锭中夹杂物的分布及熔池深度变化进行了测定。根据试验结果对滚球钢中夹杂物在重熔过程中的去除机理进行了初步的探讨与分析。

By the superposition of thin films on a polished and lightly etched surface of a metallic specimen,different colours will appear under the microscope through the interference of white light by thin films.Thus the contrast between the different phases on the surface of the specimen is enhanced,enabling the differentiation and resolution between them. The method used is simplely either by swabbing a thin oil film or by dropping a 1-2% solution of colloidion solution or similiar materials on the surface of the...

By the superposition of thin films on a polished and lightly etched surface of a metallic specimen,different colours will appear under the microscope through the interference of white light by thin films.Thus the contrast between the different phases on the surface of the specimen is enhanced,enabling the differentiation and resolution between them. The method used is simplely either by swabbing a thin oil film or by dropping a 1-2% solution of colloidion solution or similiar materials on the surface of the spicemen,If the films so produced are of proper thicknesses,then different colours will appear on the various phases as the results of either distruction or strengthening of certain wave Iengths of white Iight. In the paper the mechanisn of thin film interference is also discussed and the different features of colour metallography are outlincd. In order to evaluate the advantages of this method of superposition other currently used colour methods are compared.

本文叙述在金相试样上如何利用“附加薄膜”方法并通过薄膜的干涉作用在试样表面产生不同的彩色以提高各个相的对比度,有利于复杂的显微结构和多相结构的分析和鉴别。这个方法是在预先抛光好的及经过轻度蚀刻的试样表面上涂上一层油膜,成者在试样上滴上稀释的塑料溶液使之成为薄膜。文中讨论了在白光照射下薄膜发生干涉的机理及如何产生不同的彩色以将各个相区别开来。同时还讨论有关彩色金相学中所出现的若干问题。最后又将这一“附加薄膜”方法和其他现行的彩色金相方法比较,得出恰当的评价。
