Bimetallic Al-Ag, Al-Cu and Al-Zn nanoparticles with controllable phase compositions prepared by the electrical explosion of two wires

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 divided by 1.82 mu s, 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. (C) 2020 Elsevier B.V. All rights reserved.
