| 摘 要： | 利用机械活化-放电等离子（MASPS）的方法，将铁粉、铝粉和Al2O3粉的混合粉末通过高能球磨进行机械活化，并利用放电等离子快速烧结得到FeAl／Al2O3块体材料，讨论了Al2O3的活化作用及烧结工艺对复合材料组织与性能的影响。结果表明：利用MASPS法可以制备出致密且晶粒细小的FeAl／Al2O3纳米复合材料，最高致密度可以达到96.4％。

| Abstract: | Method of mechanically activated spark plasma sintering (MASPS) was used. First, the powders of Fe, Al and Al2O3 were activated by high energy ball-milling. Then the powders were synthesized and Consolidated by spark plasma sintering machine. The activation function of Al2O3, the influence of the sintering process on microstructure and properties of the composite were discussed. The results indicated that FeAl/Al2O3 nano-composites with fine grains and high density could be obtained by MASPS, and the highest density was 96. 4%. |
