2016年1月15日 · In order to refine the grain size of WC and to improve the mechanical properties, VC and NbC as grain growth inhibitors, were added to WC–6Co FGCCs. The grain growth kinetics of WC was investigated, and both the room temperature and high temperature mechanical properties were tested.

2008年8月15日 · Preliminary work revealed that up to 5 wt.% NbC addition effectively inhibits WC grain growth, resulting in an increased room temperature hardness, toughness and flexural strength compared to plain WC–12 wt.% Co hardmetal.

结果表明：利用 MC（M=Ti, V, Nb）与 WC 的密度差异，实现了涂层中碳化物颗粒增强相的均匀分布。 与 Nb 不同，Ti 和 V 参与未熔 WC 周边凝固组织的形成，使其形貌由矩形块状分别转变为弥散环绕颗粒和放射状圆润柱晶。

在满足点阵类型、电化因素和尺寸因素三条件时，其中的金属原子可互相置换，如TiC–VC系形成(Ti、V)C；VC–NbC系形成(Nb、V)C；TiC–ZrC系形成(Ti、Zr)C等。

2021年9月13日 · In the present study, WC-10Co with TiC, VC and (Ta, Nb)C as the inhibitors to the grain growth was prepared using high energy ball milling and the subsequent HIP process at various temperatures.
