Abstract

Abstract In this paper, an attempt to estimate the stage of the fatigue process using the Barkhausen noise method is studied. First, microstructural and static tensile tests were carried out and, subsequently, fatigue tests up to failure were conducted. After determination of the material behaviour in the assumed static and dynamic conditions, the interrupted fatigue tests were performed. Each specimen was stressed up to a different number of cycles corresponding to 10%, 30%, 50%, 70% and 90% of fatigue lifetime for the loading conditions considered. In the next step of the experimental programme, the specimens were subjected to the Barkhausen magnetic noise measurements. Various magnetic parameters coming from the rms Barkhausen noise envelopes were determined. The linear relationship betweenthe full-width at half-maximum (FWHM) of the Barkhausen noise envelope and the number of loading cycles to fracture was found. Specimens loaded up to a certain number of cycles were also subjected to a tensile test to assess an influence of fatigue on the fracture features.

用巴克豪森噪声法评估中碳钢的疲劳行为

摘要本文研究了使用巴克豪森噪声法估算疲劳过程阶段的尝试。首先进行了微观结构和静态拉伸试验，随后进行了直至失效的疲劳试验。在确定材料在假定的静态和动态条件下的行为后，进行了间断疲劳试验。在所考虑的加载条件下，每个试样的受力循环次数分别为疲劳寿命的 10%、30%、50%、70% 和 90%。实验计划的下一步是对试样进行巴克豪森磁噪声测量。根据巴尔豪森噪声包络线的均方根值确定了各种磁参数。发现巴尔豪森噪声包络的半最大值全宽（FWHM）与到断裂为止的加载循环次数之间存在线性关系。加载到一定循环次数的试样还进行了拉伸试验，以评估疲劳对断裂特征的影响。

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.
