Abstract

This research aims to investigate the application of the hot pressing (HP) sintering process in the fabrication of W-B-Fe-Cr-C advanced shielding materials and analyze the relationship between their microstructure and mechanical properties. The findings reveal that the HP sintering process can effectively produce reactive sintered boride (RSB) materials with high density and engineering application size. The results indicate that the residual stress in RSB-HP improves its bending strength to some extent. Residual stress and granular structure are both related to phase aggregation during sintering. Microstructural analysis has unveiled the granular organizational characteristics and the pathways of crack propagation within the RSB-HP. These discoveries hold significant importance for comprehending the potential of the HP sintering process in the context of nuclear fusion shielding material preparation and provide a scientific foundation for further optimizing the sintering process and performance of RSB materials.

热压烧结钨基先进屏蔽材料的机械特性研究

本研究旨在探讨热压（HP）烧结工艺在制造 W-B-Fe-Cr-C 高级屏蔽材料中的应用，并分析其微观结构与机械性能之间的关系。研究结果表明，热压烧结工艺能有效生产出具有高密度和工程应用尺寸的反应烧结硼化物（RSB）材料。结果表明，RSB-HP 中的残余应力在一定程度上提高了其抗弯强度。残余应力和颗粒结构都与烧结过程中的相聚集有关。微结构分析揭示了 RSB-HP 中的颗粒组织特征和裂纹扩展途径。这些发现对于理解 HP 烧结工艺在核聚变屏蔽材料制备方面的潜力具有重要意义，并为进一步优化 RSB 材料的烧结工艺和性能奠定了科学基础。
