Abstract
Frangible firearm projectiles, firearm cartridges containing the same, and methods for forming the same. The firearm projectiles are formed from compacted metal powders that may include an anti-sparking agent. The compacted metal powders may be or include a compacted mixture of metal powders that may include powders of one or more of iron, zinc, bismuth, copper, tungsten, nickel, boron, and/or alloys thereof, and/or oxides thereof. The compacted mixture may be heat treated for a time sufficient to form a plurality of discrete alloy domains within the compacted mixture. The frangible firearm projectile may be formed by a mechanism that includes vapor-phase diffusion bonding and oxidation of the metal powders and that does not include forming a liquid phase of any of the metal powders or utilizing a polymeric binder. The anti-sparking agent may include a borate, such as boric acid.
