摘要

低活化铁素体/马氏体（RAFM）钢被广泛认为是熔覆层组件的首选结构材料。在中国的主要候选材料中，中国低活化铁素体/马氏体（CLF-1）钢需要进一步研究其热力学行为，这对其在聚变反应堆包层中的应用至关重要。本研究考察了温度和应变速率对CLF-1钢变形行为的影响。通过热加工图、显微组织演变分析和能效评价，确定了应变为0.2时CLF-1钢的最佳稳定变形条件。这些条件对应于应变速率为0.1至5 s−1，温度范围为1273至1373 K。这些稳定变形参数的识别为优化临界CLF-1钢的热加工工艺提供了理论依据。

Investigation of thermoplastic deformation behavior and microstructural evolution of CLF-1 steel for fusion blankets

Reduced Activation Ferritic/Martensitic (RAFM) steel is widely recognized as the preferred structural material for fusion blanket modules. Among China’s primary candidate materials, Chinese Low-Activation Ferritic/Martensitic (CLF-1) steel requires further investigation of its thermomechanical behavior, which is crucial for its application in fusion reactor blankets. This study examines the effects of temperature and strain rate on the deformation behavior of CLF-1 steel. By using a hot processing map, microstructural evolution analysis, and energy efficiency evaluation, the optimal stable deformation conditions for CLF-1 steel at a strain of 0.2 are identified. These conditions correspond to a strain rate of 0.1 to 5 s⁻¹ and a temperature range of 1273 to 1373 K. The identification of these stable deformation parameters provides a theoretical foundation for optimizing the hot-working process of critical CLF-1 steel.
