摘要

采用粉末冶金法制备了Ti(C，N)-Fe硬质合金，高熵陶瓷（HEC）粉末部分取代Ti（C，N）作为硬质相。研究了HEC粉末对Ti(C，N)-Fe硬质合金显微组织和力学性能的影响。实验结果表明，随着HEC含量的增加，硬相颗粒的形貌由球形转变为多边形。此外，Ti（C，N）基碳化物的边缘相和粘结相呈半共格关系，表明界面结合较强。值得注意的是，当HEC添加量为5 wt%时，硬相和粘结相之间的结合强度达到最佳。

Effect of high-entropy powders on “rim-core” structure and properties of Ti(C,N)-Fe cemented carbide

Ti(C,N)-Fe cemented carbide, which high-entropy ceramic (HEC) powder partially replaces Ti(C,N) as the hard phase, was fabricated via powder metallurgy. This study investigates the influence of HEC powder on the microstructure and mechanical properties of Ti(C,N)-Fe cemented carbide. Experimental results indicate that with the increasing of HEC content, the morphology of hard-phase particles transitions from spherical to polygonal. Additionally, the rim phase and the binder phase in the Ti(C,N)-based carbide exhibit a semi-coherent relationship, suggesting a strong interfacial bonding. Notably, the optimal bonding strength between the hard phase and binder phase is achieved at 5 wt% HEC addition.
