Abstract—

Interdiffusion at the initial stage of high-temperature synthesis under the conditions of Ni nanoparticle dissolution in an Al matrix has been studied by the molecular dynamics method. Nickel and aluminum may be both in the amorphous and in the crystalline state. It has been shown that the inflammation temperature of the high-temperature synthesis reaction in the Ni−Al system drops much faster when nickel is in the amorphous state. At constant temperature, the rate of interdiffusion has been shown to be almost independent of the aluminum structure (crystalline or amorphous).

Ni纳米颗粒在铝基体中溶解时高温合成初始阶段相互扩散的分子动力学模拟

摘要-

采用分子动力学方法研究了纳米镍颗粒溶解在铝基体中的条件下高温合成初期的相互扩散。镍和铝可以处于非晶态和晶态。研究表明，当镍处于非晶态时，Ni−Al 体系中高温合成反应的燃烧温度下降得更快。在恒定温度下，相互扩散速率已被证明几乎与铝结构（结晶或非晶）无关。
