Abstract

Online non-destructive magnetic monitoring is used to control the quality of steels subjected to multiaxial stresses. Due to magnetoelastic effects, a correction of non-destructive signal is necessary requiring the use of predictive magnetoelastic models on the one hand, and magnetoelastic measurements carried out under biaxial stress conditions on the other hand. Among magnetoelastic properties, magnetostriction under stress is particularly discriminent for models and the development of set-ups allowing for this measurement looks relevant. The first measurements of magnetostriction of a low carbon steel under biaxial stress have been reported in Hubert et al. (2023). This set-up shows several drawbacks among which a low magnitude and inhomogeneous magnetic field. In this study, an improvement of the previous biaxial set-up is first proposed. Anhysteretic and cyclic magnetic and magnetostrictive measurements of a dual-phase (DP) steel are reported next. An analytical approach of the magnetoelastic modeling is proposed on the other hand, leading to the proposition of new equivalent stress formulations applicable for magnetostriction.

DP钢在双轴机械加载条件下的磁弹性行为。磁致伸缩的等效应力

采用在线无损磁监测技术对受多轴应力作用的钢进行质量控制。由于磁弹性效应，非破坏性信号的校正一方面需要使用预测磁弹性模型，另一方面需要在双轴应力条件下进行磁弹性测量。在磁弹性特性中，应力下的磁致伸缩对于模型来说是特别有区别的，并且允许这种测量的设置的发展看起来是相关的。Hubert等人（2023）首次报道了低碳钢在双轴应力下的磁致伸缩测量。这个装置显示出几个缺点，其中一个低强度和不均匀的磁场。在这项研究中，首先提出了对先前双轴设置的改进。本文还报道了一种双相（DP）钢的非迟滞、循环磁性和磁致伸缩测量。另一方面，提出了一种磁弹性建模的解析方法，从而提出了适用于磁致伸缩的新的等效应力公式。

期刊介绍： The Journal of Magnetism and Magnetic Materials provides an important forum for the disclosure and discussion of original contributions covering the whole spectrum of topics, from basic magnetism to the technology and applications of magnetic materials. The journal encourages greater interaction between the basic and applied sub-disciplines of magnetism with comprehensive review articles, in addition to full-length contributions. In addition, other categories of contributions are welcome, including Critical Focused issues, Current Perspectives and Outreach to the General Public. Main Categories: Full-length articles: Technically original research documents that report results of value to the communities that comprise the journal audience. The link between chemical, structural and microstructural properties on the one hand and magnetic properties on the other hand are encouraged. In addition to general topics covering all areas of magnetism and magnetic materials, the full-length articles also include three sub-sections, focusing on Nanomagnetism, Spintronics and Applications. The sub-section on Nanomagnetism contains articles on magnetic nanoparticles, nanowires, thin films, 2D materials and other nanoscale magnetic materials and their applications. The sub-section on Spintronics contains articles on magnetoresistance, magnetoimpedance, magneto-optical phenomena, Micro-Electro-Mechanical Systems (MEMS), and other topics related to spin current control and magneto-transport phenomena. The sub-section on Applications display papers that focus on applications of magnetic materials. The applications need to show a connection to magnetism. Review articles: Review articles organize, clarify, and summarize existing major works in the areas covered by the Journal and provide comprehensive citations to the full spectrum of relevant literature.
