초록 ▼

A projectile, including a compacted and sintered mixture of a plurality of tungsten particles and a plurality of iron particles. At least a portion of the plurality of iron particles are bonded together, and no intermetallic compounds or alloys of the tungsten particles and iron particles are formed during the compaction and sintering processes. The final density of the projectile is from about 8.1 grams per cubic centimeter to about 12.1 grams per cubic centimeter, and no substantial densification occurs during sintering. A method of producing such a projectile is also disclosed.

대표청구항 ▼

The invention claimed is: 1. A method of producing a projectile, comprising the steps of: providing a plurality of tungsten particles that are from about 8 microns to about 30 microns in diameter and a plurality of iron particles that are from about 40 microns to about 200 microns in size; mixing the plurality of tungsten particles and the plurality of iron particles; blending the tungsten particles and the iron particles; mechanically compacting the mixture in a die, thereby forming the projectile; and sintering the formed projectile in a sintering furnace under controllable atmospheric conditions and at a temperature sufficient to form bonds between at least a portion of the plurality of iron particles, the temperature being from about 1500° F. to about 2450° F., wherein no intermetallic materials or alloys of the tungsten particles and the iron particles are formed during the compacting and sintering steps due to the sintering temperature and to the size of the tungsten particles and the size of the iron particles utilized; wherein the final density of the projectile is from about 8.0 grams per cubic centimeter to about 12.2 grams per cubic centimeter and the final hardness of the projectile is from about 10 HB to about 50 HB; wherein densification is achieved when the mixture is compacted due to mechanical bond formation between the plurality of tungsten particles and the plurality of iron particles and no substantial densification occurs in the sintering step; and wherein the ratio of the mixture of tungsten particles to iron particles is, by weight, from about 30:70 to about 65:35. 2. The method of claim 1, wherein the tungsten particles are in the form of a tungsten powder. 3. The method of claim 1, wherein the iron particles are in the form of an iron powder. 4. The method of claim 1, wherein the iron particles are at least one of water-atomized iron particles, sponge iron particles and iron powder. 5. The method of claim 1, further comprising the step of adding a material additive to the mixture of tungsten particles and iron particles. 6. The method of claim 5, wherein the material additive is at least one of a chemical compound, a polymeric compound, a binder and a lubricant. 7. The method of claim 5, wherein the chemical additive is a lubricant, the method further comprising the step of adding the lubricant to the mixture of the tungsten particles and the iron particles, wherein the lubricant comprises up to 1% by weight of the mixture. 8. The method of claim 5, wherein the material additive is at least one of ethylenebissterimide, lithium carbonate, a carbonate compound, a stearate compound, copper stearate and zinc stearate. 9. The method of claim 1, wherein the sintering step is a solid state sintering process. 10. The method of claim 1, wherein the formed and sintered projectile is a shot pellet. 11. The method of claim 1, wherein the formed and sintered projectile is a bullet. 12. The method of claim 1, wherein the final hardness of the formed and sintered projectile is less than the final hardness of steel shot. 13. A projectile made in accordance with the method of claim 1.
