NOVEL MATERIALS FOR THE PRODUCTION OF ENVIRONMENTALLY-FRIENDLY AMMUNITION AND OTHER APPLICATIONS.

摘要

The invention relates to an ODS (oxide-dispersion-strengthened or particulate dispersion) type of material comprising a metal alloy matrix containing a dispersion of distributed reinforcement particles which impart optimal density and deformability to the material. The metal matrix comprises an alloy of zinc and bismuth, zinc and aluminium, tin and bismuth or tin and zinc and the reinforcement material comprises wolfram, ferrowolfram, oxides of both, carbides of both or derivatives thereof. The inventive material can be used to replace lead in the production of environmentally-friendly ammunition, fishing hooks, motor vehicle counterweights, X-ray and ionising radiation screens, golf clubs, waterworks and plumbing systems, as well as for electric and magnetic applications. The invention also relates to environmentally-friendly ammunition produced using the material comprising, for example, pellets.
