Structural Features of Pseudoalloys Formed in the Course of Explosive Compaction of Ni–Ag and Fe–Pb Bimetallic Nanoparticles

Resumo

The paper examines the bulk nanostructured alloys (pseudoalloys) produced by method of shock-wave impact upon Ni–Ag 9 wt% and Fe–Pb 27 wt% bimetallic nanopowders. The authors examined the structure and particle size distribution of the original Ni–Ag and Fe–Pb bimetallic nanoparticles produced by method of electrical explosion of wires. The structure and hardness of these bulk nanostructured alloys were analyzed. The results presented in the paper indicate the feasibility of application and efficiency of shock-wave compaction for production of compacts from bimetallic nanoparticles.
