Abstract
Frangible firearm projectiles, firearm cartridges containing the same, and methods for forming the same. The firearm projectiles are formed from a compacted mixture of metal powders that includes zinc and iron powders and which may include an anti-sparking agent. The compacted mixture is 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. A majority component of the frangible firearm projectile may be iron. One or more of zinc, bismuth, tin, copper, nickel, tungsten, boron, and/or alloys thereof may form a minority component of the frangible firearm projectile. The anti-sparking agent may include a borate, such as boric acid.
