摘要
FIELD: ammunition for sports and training shooting. SUBSTANCE: bullet is made of mixture of metal particles and basic material of metal or metalloid binder. Required shape is given to bullet as result of compaction and heating to temperature exceeding temperature needed to form at least one intermetal compound but not reaching temperature of interconnection of metal particles as result of sintering and temperature of formation of substantial quantities of soft alloy of metal particles and basic material of metal or metalloid binder and subsequent cooling. Bullets manufactured according to this invention display sufficient strength to maintain their integrity in process of ignition of powder charge but disintegrate into powder after collision. EFFECT: manufacture of bullets without use of lead. 28 cl, 2 dwg
