Abstract
The microstructure, deformation characteristics, and electric conductivity of composites produced by explosive compaction of a copper–molybdenum powder mixture were studied. It is shown that an increase in detonation velocity during explosive treatment leads to an increase in crystal lattice microstrains and dispersivity of the block structure. This favors the plastic deformation of the particles, mainly copper particles, activation and weldability of their boundaries, which increases the conductivity of the compacts produced. Optimal conditions of explosive compaction and heat treatment for production of composites with high conductivity are found. Key words: powder mixture, planetary mill, explosive compaction, heat treatment, electric conductivity, x-ray structural analysis.
