The effects of (0–60%) vol% (70 vol% ZrB₂ + 30 vol% SiC) additions on microstructure and properties of NbMo substrate fabricated by hot-pressing were studied at room temperature. Types of formed phase were decided by the amount of ZrB₂ and SiC additives. The effective eutectic phase was observed in 15 vol% (70 vol% ZrB₂ + 30 vol% SiC)-NbMo, which was attributed to the addition of SiC. 30 vol% (70 vol% ZrB₂ + 30 vol% SiC)-NbMo had the highest relative density of 98.69%. Compared with x ZrB₂-NbMo composites, the addition of SiC could further improve the hardness of NbMo_ss in x (70% ZrB₂ + 30% SiC)-NbMo when the value of x was same, and NbMo_ss in 60 vol% (70 vol% ZrB₂ + 30 vol% SiC)-NbMo had the highest hardness of 6.82 GPa. Only the 15 vol% (70 vol% ZrB₂ + 30 vol% SiC) addition could improve the compressive strength of NbMo matrix. The reasons for the low strength of 30, 45, 60 vol% (70% ZrB₂ + 30% SiC)-NbMo were the lack of ductile phase and the large amount of hard phase production.

 在室温下研究了添加（0-60％）（体积）（70％（体积）ZrB ₂ + 30 ％（体积）SiC）对通过热压制备的NbMo衬底的组织和性能的影响。形成相的类型取决于ZrB ₂和SiC添加剂的量。在15vol％（70vol％的ZrB ₂  + 30vol％的SiC）-NbMo中观察到有效的共晶相，这归因于SiC的添加。30体积％（70体积％的ZrB ₂  +30体积％的SiC）-NbMo的最高相对密度为98.69％。与x ZrB ₂ -NbMo复合材料相比，当x的值相同时，添加SiC可以进一步提高x（70％ZrB ₂  + 30％SiC）-NbMo中NbMo _ss的硬度，而NbMo _ss在60体积％（70体积％的ZrB ₂  +30体积％的SiC）中，NbMo的最高硬度为6.82GPa。仅15体积％（70体积％的ZrB ₂  +30体积％的SiC）的添加可以提高NbMo基体的抗压强度。 30、45、60 ％（体积）（70％ZrB ₂ + 30％SiC）-NbMo的强度低的原因是缺乏韧性相和大量产生硬相。
