摘要： The invention relates to bullets having increased frangibility (or which can be easily fragmented) and to powder materials and processes for the manufacture of such bullets. The bullets of the present invention are made from an iron alloy containing 75-81% Hoeganaes MH-100 Iron 0.6-0.09% Carbon, and balance of admixed Copper powder. Said bullets are then coated for lubricity so the bullet does not prematurely wear the barrel of a gun. Additionally, the invention provides a simple low cost process to make bullets that is amenable to mass production via automation.

摘要： To produce lead-free projectiles, iron and copper are melted at a predetermined ratio and rapidly quenched to yield a fine-grained microstructure with uniformly distributed copper and iron phases. The iron-copper alloy may be made into a powder through atomization, with the iron-copper molten metal being dispersed using a rapidly moving gas, liquid stream, or via mechanical dispersion. The step of forming the bullet may include solid-state sintering of the atomized powder, including heating at a temperature below 1083° C., the melting point of copper. Alternatively, the step of shaping the mixture into a bullet-shaped form may include casting and/or uniaxially pressing the mixture into a mold. A ceramic powder may be added to the copper-iron mixture prior to forming to produce a frangible projectile. Chromium, including chromium from recycled stainless steel, may be added to increase corrosion resistance and/or reduce manufacturing cost.

摘要： A projectile can be fired at a surface vessel and, upon impact, an air bag may be deployed almost instantaneously from underneath the vessel. Through the rapid inflation of the air bag, the stability and orientation of the target surface vessel may be disturbed. Disturbance, at a minimum, may reduce and change the trajectory of the surface vessel, but, in some circumstances, the surface vessel may be overturned. The air bag may be designed with an anti-slip coating to directly couple to the wet hull of the surface vessel. In some embodiments, the projectile may include a delay to enable the air bag to be positioned under the vessel before inflation thereof.
