采用反应铸造法制备了含VC、TiC颗粒的Fe3Al基合金 ,并研究了颗粒相的加入对Fe3Al合金组织结构和力学性能的影响。研究表明 ,TiCp 可以细化Fe3Al合金铸锭组织 ,而VCp 的作用不明显 ,但可以细化热加工后的再结晶组织 ;同时发现 ,颗粒相的加入提高了Fe3Al合金在室温和 6 0 0℃下的屈服强度 ,而延伸率有稍许下降 ,并改变了合金的断裂模式 The Fe3Al-based alloys containing VC and TiC particles were prepared by reactive casting. The effects of the addition of particles on the microstructure and mechanical properties of Fe3Al alloy were also studied. The results show that TiCp can refine the Fe3Al alloy ingot structure, while the effect of VCp is not obvious, but can refine the recrystallized microstructure after hot working; also found that the addition of particulate phase increases Fe3Al alloy at room temperature and 600 ℃ Under the yield strength, while the elongation has a slight decline, and changed the alloy fracture mode
