Abstract
The explosive compaction of chromium carbide (Cr3C2) and titanium powder mixtures is investigated. The phase composition of fabricated alloys was studied using electron probe microanalysis. It is found that the chemical composition of alloy components undergoes no changes and no redistribution of elements between occurs. The effect of explosive loading modes on the porosity and hardness of powder materials is revealed. It is shown that the explosion compaction of high-melting carbides and metals powder mixtures makes it possible to form consolidated hard alloys during the compacting stage. Formation features of interfaces between material components during shock-wave processing were investigated using electron microscopy. It was revealed that, in order to form strong interfacial surfaces, it is necessary that the powder heating temperature during the shock wave compression would exceed (0.35–0.4)Tm, where Tm is the melting temperature of the base carbide of the alloy.
