Abstract

The multi-component phase diagrams, microstructure and correlated mechanical properties of recently developed NbC-Ni based cermets are described, allowing to elucidate the correlations between composition, microstructure and mechanical properties, and address some potential applications. The influence of the carbon content, binder content, and secondary carbide additions on the microstructure and mechanical properties of NbC-based cermets are presented in detail. The reported materials focus on NbC-Ni matrix grades with 6–20 wt% Ni binder and 4–20 wt% (VC, Mo2C, WC, TiC, and/or Ti(CxNy)) additions densified by liquid phase sintering in vacuum. The results revealed that the NbC grain growth was significantly limited by some combinations of carbide or carbonitride additions, strongly influencing the mechanical properties. The NbC-based cermets offer mechanical properties that would allow them to partially replace WC-Co and Ti(C,N)-Ni in some specific wear resistant applications.

基于 NbC-Ni 的金属陶瓷：相图、微观结构和机械性能

本文描述了最近开发的 NbC-Ni 基金属陶瓷的多组分相图、微观结构和相关机械性能，从而阐明了成分、微观结构和机械性能之间的相关性，并探讨了一些潜在的应用领域。详细介绍了碳含量、粘合剂含量和二次碳化物添加量对 NbC 基金属陶瓷微观结构和机械性能的影响。所报道的材料主要集中在镍粘结剂含量为 6-20 wt%、添加量为 4-20 wt%（VC、Mo2C、WC、TiC 和/或 Ti(CxNy)）的 NbC-Ni 基体牌号上，这些牌号是通过真空液相烧结致密的。结果表明，碳化物或碳氮化物添加物的某些组合极大地限制了 NbC 晶粒的生长，从而严重影响了其机械性能。基于 NbC 的金属陶瓷具有良好的机械性能，可在某些特定的耐磨应用中部分取代 WC-Co 和 Ti（C，N）-Ni。

期刊介绍： The International Journal of Refractory Metals and Hard Materials (IJRMHM) publishes original research articles concerned with all aspects of refractory metals and hard materials. Refractory metals are defined as metals with melting points higher than 1800 °C. These are tungsten, molybdenum, chromium, tantalum, niobium, hafnium, and rhenium, as well as many compounds and alloys based thereupon. Hard materials that are included in the scope of this journal are defined as materials with hardness values higher than 1000 kg/mm2, primarily intended for applications as manufacturing tools or wear resistant components in mechanical systems. Thus they encompass carbides, nitrides and borides of metals, and related compounds. A special focus of this journal is put on the family of hardmetals, which is also known as cemented tungsten carbide, and cermets which are based on titanium carbide and carbonitrides with or without a metal binder. Ceramics and superhard materials including diamond and cubic boron nitride may also be accepted provided the subject material is presented as hard materials as defined above.
