This examination is aimed to study the various densification mechanisms in the ZrB₂-SiC system at different sintering temperatures. For such an objective, hot-pressing process was implemented to fabricate three ceramics at sintering temperatures of 1650, 1850, and 2050 °C under 10 MPa for 1 h. According to the results, particle rearrangement and fragmentation were the predominant densification mechanisms at the lowest sintering temperature. Additionally, it was found that the activation of the liquid phase sintering mechanism was advantageous in the particle rearrangement at low temperatures. However, rising the sintering temperature to 1850 °C changed the dominant mechanism to the plastic deformation. Such a phenomenon was accompanied by the creation of many dislocations in both ZrB₂ and SiC grains. Implementing a higher sintering temperature (2050 °C) activated another consolidation mechanism called diffusion. This occurrence, together with the evaporation of the majority of the liquid phase at elevated temperatures, resulted in emerging transgranular fracture mode in the sample.

这项检查旨在研究ZrB ₂ -SiC系统在不同烧结温度下的各种致密化机理。为了实现这一目标，实施了热压工艺，以在1650、1850和2050℃的烧结温度下，10 MPa下烧结1 h来制造三种陶瓷。根据结果​​，在最低烧结温度下，颗粒重排和破碎是主要的致密化机理。另外，发现液相烧结机制的激活在低温下的颗粒重排中是有利的。但是，将烧结温度提高到1850°C改变了塑性变形的主要机理。这种现象伴随着ZrB ₂中许多位错的产生和SiC晶粒。实施更高的烧结温度（2050°C），激活了另一种称为扩散的固结机制。这种现象，再加上大多数液相在高温下的蒸发，导致样品中出现了经晶断裂模式。
