中文摘要：
采用机械合金化及退火工艺制备纳米级Fe3Al金属间化合物粉体；利用有机前驱体烧蚀技术，氩气保护下在真空热处理炉中经过1460℃热处理，制备具有高气孔率、高尺寸稳定性、耐高温的Fe3Al金属间化合物网状结构；采用负压浸渗法制备Al／Fe3A1网状结构复合材料，材料的耐磨性能明显优于基体材料，在100N载荷、400r／min转速的试验条件下，摩擦时间为20min时，Al/Fe3Al复合材料的磨损量较纯Al试样降低66％。
英文摘要：
Fe3Al were prepared by combined processing by mechanical alloying and annealing. Fe3Al intermetallics Network Structure（NS） ,processing high porosity and dimension stability was fabricated by precursor ablation technology. The precursor were subjected to the thermal treatment at 1460℃ under the protection of argon atmosphere. The molten Al completed the infiltration into the porous TiAI at the traction of negative pressure. Al/Fe3Al network composites exhibited better performance than Al base. Al/Fe3Al network composites＇s wear extent minish 66% then Al in 100N load,400r/min and 20 min wear time.
