Abstract

Mechanical properties of steels are closely related to microstructures. However, in steel process there is a lack of effective online monitoring and characterized methods for steel microstructures and mechanical properties, giving rise to issues of low steel quality and high alloy costs (to ensure mechanical strength). In order to ensure the mechanical performance of steels, advanced characterization methods and measurement instruments are necessary for real-time online monitoring of the production process. In this study, electromagnetic responses on steel microstructures and mechanical properties are investigated. An online electromagnetic non-destructive characterization system for steel microstructures is developed. Relationships between microstructures and steel mechanical properties have been demonstrated through mechanical performance tests. Therefore, the electromagnetic non-destructive characterization system can be used for real-time online monitoring of mechanical properties of steels.

摘要

钢的力学性能与微观结构密切相关。然而，在钢铁生产过程中，缺乏有效的在线监测以及针对钢的微观结构和力学性能的表征方法，从而导致钢质量低下和合金成本高昂（以确保机械强度）的问题。为了确保钢的机械性能，先进的表征方法和测量仪器对于生产过程的实时在线监测是必不可少的。在本研究中，对钢的微观结构和力学性能的电磁响应进行了研究。开发了一种用于钢微观结构的在线电磁无损表征系统。通过力学性能测试证明了微观结构与钢力学性能之间的关系。因此，电磁无损表征系统可用于钢力学性能的实时在线监测。
