ABSTRACT This research aims to determine consistent patterns in the formation of structure-phase states of bimetallic nanoparticles in the course of non-synchronous electrical explosion of two intertwined wires made of dissimilar metals (EEIW). It was shown by the example of Al Ag, Al Cu and Al Zn binary systems that EEIW can be used to obtain bimetallic nanoparticles with controllable phase composition. The phase composition of the nanoparticles is determined by the ratio between the diameters of the exploded wires. It was found that if the interval between non-synchronous explosions lies within 0.0 ÷ 1.82 μs, then the nanoalloying of clusters during coagulation is not limited. The research findings can be used for making use of EEIW to obtain a wide range of bimetallic nanoparticles with controllable phase composition.

两根线电爆炸制备的相组成可控的双金属Al Ag、Al Cu和Al Zn纳米颗粒

摘要 本研究旨在确定在由异种金属 (EEIW) 制成的两条相互缠绕的导线的非同步电爆炸过程中双金属纳米粒子结构相状态形成的一致模式。以Al Ag、Al Cu和Al Zn二元体系为例表明,EEIW可用于获得相组成可控的双金属纳米粒子。纳米粒子的相组成由爆炸丝直径之间的比率决定。发现如果非同步爆炸之间的间隔在 0.0 ÷ 1.82 μs 内,则凝聚过程中团簇的纳米合金化不受限制。该研究成果可用于利用EEIW获得各种相组成可控的双金属纳米粒子。
