| 中文摘要: |
| Ni/Al复合材料是制备NiAl金属间化合物的重要原料,同时也是一种典型的结构能源双功能材料.本文主要采用管式电阻炉测试了Ni/Al复合材料的起始反应温度,研究了样品状态、粉末粒径、Al/Ni摩尔比、测试气氛、第三相等对材料起始反应温度的影响.结果表明:压制态的Ni/Al复合材料的起始反应温度比粉末态的要低；Ni/Al复合材料的起始反应温度随粉末粒径的降低而降低,随Al/Ni摩尔比的增大先升高后降低；空气气氛下的起始反应温度高于惰性气氛下的；添加W可提高材料的起始反应温度,而添加Mg则降低材料的起始反应温度. |

| Ni/Al composite is a typical dual functional structural energetic material,which is often used to prepare intermetallic compound.The initial reaction temperatures of Ni/Al composites were measured using tubular resistance furnace in this paper.And the effects of the sample status,particle size,molar ratio of Al to Ni,atmosphere and the third phase on the initial reaction temperature were studied.Results show that the initial reaction temperature of Ni/Al compact is lower than that of the Ni/Al mixture powders.The initial reaction temperature of Ni/Al composite decreases with the decrease of the particle size,and increases with the increase of molar ratio Al to Ni and then decreases after the first increased.The initial reaction temperature measured under inert atmosphere is higher than that measrued under air atmosphere.Addition of W can increase the initial reaction temperature of the composite material,but the addition of Mg results in reducing of the initail reaction temperature. |
