摘　　要：利用放电等离子烧结技术制备具有塑性变形性能的Fe-6．5％（质量）Si复合材料。首先利用机械合金化技术制备具有包覆结构的Fe-Si复合粉，然后将这种复合粉在400-700℃下进行放电等离子烧结。用电子探针对烧结块体及轧制后的片材进行微观分析。结果表明，所制备的Fe-6．5％（质量）Si复合材料保持了复合粉的原始特性，具有良好的塑性变形性能。这种复合材料可以在室温轧制成片材。Fe-6.5wt%Si composite materials with plasticity were prepared by Spark Plasma Sintering. The composite powders of Fe coated with Si were prepared by Mechanical Alloying firstly. Then the composite powders were sintered by Spark Plasma Sintering at 400-700℃. The sintered samples and rolled samples were analyzed with EPMA. The results indicate that the sintered Fe-6.5wt%Si composite preserves the plastic deformation property of the original powders, which can be rolled into sheet at room temperature.
