WC-Ni基硬质合金用作磁性材料成形模具、核主泵机械密封关键部件以及磨蚀性服役工况耐磨零件独具优势。由于材料体系的本征特性,与WC-Co合金相比,在黏结金属含量相同和合金晶粒度相近条件下,WC-Ni基合金强度、硬度和韧性均明显较低,高性能化面临挑战。本文对WC-Ni三元合金和含其它合金组元WC-Ni基合金的微观结构和物理力学性能调控,以及含Ti板状晶WC-Ni基合金的研究进展进行综述,旨在奠定高性能WC-Ni基硬质合金新材料高效开发的基础。
Research Progress on Microstructure and Physical and Mechanical Properties Control of WC-Ni-based Cemented Carbides
WC-Ni-based cemented carbides exhibit distinct advantages as magnetic material forming dies,key components in the mechanical seals of nuclear main pumps,and wear-resistant components under corrosive service conditions.Due to the intrinsic properties of the material system,the strength,hardness and toughness of WC-Ni-based cemented carbides are significantly lower compared to WC-Co-based cemented carbides with the same binder metal content and similar WC grain size.As a result,their high performance has been challenged.To lay the foundation for the efficient development of novel WC-Ni-based cemented carbides with enhanced performance,in this paper we review the progress on the control of the microstructure and physical and mechanical properties of WC-Ni-based cemented carbides,including WC-Ni ternary alloys,WC-Ni-based cemented carbides with additional alloying components,and plate-grained WC-Ni-based cemented carbides with Ti.
