“…The explosive pressing of powders allows for the simultaneous production of sufficient pressures for compacting powders to a nearly pore-free state and temperatures required for consolidation (welding) of structural components of the powder materials in a single whole [3,4], which results in radically improved operating properties [5]. The short time period with high pressure and temperature prevents the possibility of a secondary chemical interaction between the alloy components and the grain growth in their structure [6,7].…”

The production of a new type of hard alloys by explosive compaction of chromium carbide (Cr3C2) and titanium powder mixtures was investigated. The phase composition of the fabricated alloys was studied using scanning electron probe microanalysis. The chemical composition of the alloy components does not change, and no redistribution of the elements was observed. The formation characteristics of the interfaces between the material components during shock wave processing were investigated using electron microscopy. The explosion compaction of high melting carbide and metal powder mixtures results in the formation of consolidated hard alloys during the compaction stage.
