Аннотация
The study aimed at revealing the main interaction regularities of powder mixtures of tungsten with a polymeric polytetrafluoroethylene matrix (PTFE) in shock-wave consolidation in cylindrical recovery fixtures. Three powder compositions based on tungsten and Teflon were subjected to shock-wave treatment: a two-component one (W + PTFE) and ones with Al and Ti + B additives. Two types of cylindrical recovery fixtures were applied: ones with continuous filling and ones with a central rod. A significant effect of the “activating” additives (Al, Ti, B) on the initiation and the process of the chemical reaction in the powder mixture and the final phase formation was experimentally shown.
