在1750~2100℃温度范围内，加入体积分数为0~9vol.%的MoSi2助烧剂的ZRC材料通过放电等离子烧结得到了完全固结，与块体材料相比，MoSi2的加入降低了烧结温度，细化了显微组织，提高了力学性能。硬度值为25~28 GPa，杨氏弹性系数为420~470 Gpa，弯曲强度为400~600 Mpa。(C)2008 Acta Materialia Inc.由爱思唯尔有限公司出版。版权所有。
ZrC materials containing MoSi2 as a sintering aid in the volumetric range 0-9 vol.% were fully consolidated by spark plasma sintering at temperatures between 1750 and 2100 degrees C. Addition of MOSi2 resulted in a decrease in the sintering temperature, refinement of the microstructure and improvement of the mechanical properties in comparison with the monolithic material. Hardness values were in the range 25-28 GPa, Young's modulus was in the range 420-470 GPa and the flexural strength was in the range 400-600 MPa. (C) 2008 Acta Materialia Inc.
