中文摘要：

采用Gleeble热模拟机，在电场和大热流密度作用下，研究压坯密度对Fe—V-C三元系粉末压坯燃烧合成的影响。结果表明，当压坯相对密度为73％～83％时，体系的点火温度范围为753-771℃；随压坯密度增大，体系点火温度提高，点火延迟时间增加，所达到的最高温度也有所提高；压坯密度对燃烧合成产物的相组成影响不大，均由FeC、V8C7，和V6C5组成；但随压坯密度增大，产物颗粒有所长大。

英文摘要：

The effect of compact density on combustion synthesis of Fe-V-C mixture powders based in electric field was studied using Gleeble thermal simulation equipment.The results show that the compacts with relative densities between 73%-83% can be ignited at the temperature between 753℃-771℃. With the increase of compact density, the ignition temperature becomes higher, the delay time of ignition becomes longer and the highest temperature becomes higher. Moreover, the compact density has a little influence on products, all of them consist of FeC,V8C7 and V6C5, but the product grains become bigger with the increase of compact density.
