| 英文摘要 | A dense v2alc ceramic was synthesized by an in situ reaction/hot pressing method using v, al, and c powders as starting materials. the reaction path was investigated. it was found that v2alc was produced by a reaction between al8v5 and c. single -phase v2alc could be prepared using the optimized molar ratio of v:al:c=2:1.2:0.9. the grain sizes of as-prepared v2alc samples were temperature dependent. on increasing the temperature from 1400 degrees to 1700 degrees c, the mean grain size of v2alc increased from 49 mu m in length and 19 mu m in width to 405 mu m in length and 106 mu m in width. the v2alc sample sintered at 1500 degrees c exhibited the highest flexural strength of 289 mpa and a fracture toughness of 5.7 mpa.m(1/2), while the v2alc sample prepared at 1400 degrees c showed the highest compressive strength of 742 mpa. the sample sintered at 1700 degrees c possessed the highest damage tolerance. additionally, v2alc could retain a high degree of young's modulus up to 1200 degrees c. below 800 degrees c, v2alc showed excellent thermal shock resistance. |
