Formation of Hard Alloys of Chromium Carbide and Titanium Powder Mixtures by Explosive Pressing

Abstract:

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.
