Abstract

This paper deals with the solid state diffusion bonding of X70 steel to duplex stainless steel. Microstructure and mechanical properties of the welded dissimilar steels were investigated. Optical microscopy, Electron Backscatter Diffraction, energy dispersive spectrometry, Vickers hardness measurements, and X-Ray Diffraction were the main techniques of characterization. Microtructural variation was observed in the X70 steel side compared to duplex stainless steel. The diffusion coefficient of iron, chromium, and nickel across the interface X70 steel/duplex stainless steel was also measured. The diffusion coefficient of iron and chromium is higher than that of nickel. The Vickers microhardness profile across the bond joint showed an abrupt decrease in hardness from duplex stainless steel to X70 steel. In addition, a dynamic recrystallisation reaction was observed close to the interface in the X70 steel side.

X70钢与双相不锈钢的固态扩散连接

本文研究了X70钢与双相不锈钢的固态扩散连接。研究了焊接异种钢的组织和力学性能。光学显微镜、电子背散射衍射、能量色散光谱、维氏硬度测量和X射线衍射是表征的主要技术。与双相不锈钢相比，在X70钢侧观察到微观结构变化。还测量了铁、铬和镍在X70钢/双相不锈钢界面上的扩散系数。铁和铬的扩散系数高于镍。从双相不锈钢到X70钢，整个接头的维氏显微硬度分布显示硬度急剧下降。此外，在X70钢侧的界面附近观察到动态再结晶反应。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
