摘要: 快速加热是高强度钢热处理领域的新一代先进技术,其以高效率和环保低碳等特性备受关注。近年来,感应加热技术作为一种高效、精确和可控的快速加热方法逐渐受到关注,已成为高强度钢快速热处理领域的核心研究方向。本文简要介绍了感应加热技术的发展历程和在快速热处理中的应用现状,着重讨论了快速加热技术在高强钢中的研究发展,深入探讨了影响钢材强度和韧性提升的机制。然而,与传统缓慢加热方法相比,高强度钢的快速加热过程涉及复杂的非平衡热力学行为,快速加热技术在高强度钢研究领域仍然面临诸多科学与工程挑战,如快速加热过程中的再结晶、元素扩散和固态相变等非平衡过程的组织演变及其强韧化机理,成分-工艺-组织-性能关系体系,化学界面工程/化学非均质在快速加热高强钢中的应用,大型钢板感应加热热处理试验系统及工业化试制等。

Abstract: Rapid heating is a new generation of advanced technology in the field of high-strength steel heat treatment, which has attracted much attention for its high efficiency, environmental friendliness, and low-carbon characteristics. In recent years, induction heating technology has gradually gained attention as an efficient, precise, and controllable rapid heating method, and has become a core research direction in the field of rapid heat treatment of high-strength steel. The development history of induction heating technology and its application status in rapid heat treatment were briefly introduced, the research and development of rapid heating technology in high-strength steel were discussed emphatically, and the mechanisms affecting the improvement of the strength and toughness of the steel was deeply explored. However, compared with traditional slow heating methods, the rapid heating process of high-strength steel involves complex non-equilibrium thermodynamic behaviors. The rapid heating technology still faces many scientific and engineering challenges in the research field of high-strength steel, such as the microstructure evolution and its strengthening-toughening mechanism of non-equilibrium processes (including recrystallization, element diffusion, and solid-state phase transformation) during rapid heating, the composition-process-microstructure-property relationship system, the application of chemical interface engineering/chemical heterogeneity in rapidly heated high-strength steel, as well as the induction heating and heat treatment test system for large scale steel plates and industrial trial production.

Key words: rapid heating, induction heating, high-strength steel, grain refinement, non-equilibrium phase transformation
