摘　　要：以物质的量比为1：1：3的钛粉、铝粉和TiN粉为原料，经普通混料机和不同转速高能球磨两种方式混料处理后，再在1100--1300℃真空反应烧结合成了Ti4AlN3粉体，研究了产物的物相和形貌、混合原料的物相以及烧结温度对合成Ti4AlN3的影响，确定了合成Ti4AlN3粉体的最适宜工艺。结果表明：以400r·min叫转速高能球磨3h后再在1300℃反应2h是合成Ti4AlN3粉体的最适宜工艺。Using titanium, aluminum and TiN powders with the molar ratio of 1 ： 1： 3 as raw materials, Ti4AlN3 powders were synthesized using general blender and high-energy ball milling with different rotation rates, and then were sintered at 1 100--1300 ℃ in vacuum. The phaes and morphology of products, the phase of mixed raw materials and the effect of sintering temperature on synthesis of Ti4AlN3 particles were studied and the suitable synthesis process for Ti4AlN3 particles was confirmed. The results show that the suitable synthesis process for Ti4 A1Na particles was ball milling at 400 r·min-1 for 3 h followed by sintering at 1 300 ℃ for 2 h.
