在2220~2250℃温度范围内烧结的碳化硼压坯出现了异常的晶粒长大，这与孪晶和微裂纹有关。孪晶方向为<011>。通过高温晶格常数测量确定了微裂纹与热膨胀各向异性有关。
Boron carbide compacts sintered between 2220° and 2250° C showed abnormal grain growth that was associated with twinning and microcracking. The twin direction was 〈011〉. The microcracking was linked to thermal expansion anisotropy determined by high-temperature lattice constant measurement.
