A method and apparatus for incorporating nanophase elemental materials and metastable interstitial composite materials into projectiles, projectile fragments, ordnance casings, warheads and structural components. The projectile, fragments and casings include an elemental material capable of oxidizing. A coating material that is capable of preventing oxidation of the elemental material and an oxidizing agent may be present and be capable of reacting with the elemental material so that a self-propagating high temperature synthesis reaction from a stabilized solid material is yielded for the purpose of rendering terminal effects or thermal impact to a target at impact.

What is claimed is: 1. A projectile for creating a thermal event, comprising: a bullet including an elemental material with a purity of at least 90% that is at least one of aluminum, iron, magnesium, molybdenum, titanium, tantalum, lanthanum, uranium, or zirconium; and a coating material capable of
What is claimed is: 1. A projectile for creating a thermal event, comprising: a bullet including an elemental material with a purity of at least 90% that is at least one of aluminum, iron, magnesium, molybdenum, titanium, tantalum, lanthanum, uranium, or zirconium; and a coating material capable of preventing oxidation of said elemental material, wherein at least 90% of said elemental material oxidizes within 10 seconds of removal of said coating material to produce a thermal event. 2. The projectile as in claim 1, further comprising an oxidizing agent capable of reacting with said elemental material so as to cause oxidation of said elemental material to produce the thermal event. 3. The projectile as in claim 2, wherein said oxidizing agent comprises at least one of bismuth oxides, tungsten oxides, molybdenum oxides, titanium oxides, iron oxides, magnesium oxides, including silicon, or boron. 4. The projectile as in claim 1, wherein impact of said projectile causes said elemental material to be exposed to air so as to cause oxidation of said elemental material to produce the thermal event. 5. The projectile as in claim 1, wherein said coating material surrounds said elemental material such that at least some of said elemental material is separated from others of said elemental material. 6. The projectile as in claim 1, wherein said coating material comprises at least one of polytetrafluoroethylene, perfluoroalkoxy, fluorinated ethylene propylene, polyamide, PVC vinyl, steno acid, or carbonyl acid. 7. The projectile as in claim 1, wherein said elemental material and said coating material are configured into a ballistic shape having a front end and a distal end. 8. The projectile as in claim 1, further comprising a full metal jacket surrounding said elemental material and said coating material. 9. The projectile as in claim 1, further comprising a ballast material substantially reactively inert with said elemental material and said coating material. 10. The projectile as in claim 1, wherein said elemental material and said coating material are formed into a plurality of fragments. 11. The projectile as in claim 10, wherein at least some of said plurality of fragments include a jacket that encases said elemental material and said coating material. 12. The projectile as in claim 10, wherein said plurality of fragments are contained in a sleeve or casing. 13. The projectile as in claim 10, wherein said plurality of fragments include a metal jacket that encases said elemental material and said coating material, and wherein said plurality of fragments are arranged next to one another so as to form a plurality of fitting lines that compose the whole or part of a sleeve or casing. 14. The projectile as in claim 13, further comprising: an energetic component configured to release energy so as to break apart said fragments along said fitting lines; and a stress cushion layer located intermediate said energetic component and said fragments, said stress cushion layer configured for controlling separation and directional pattern flight of said fragments. 15. The projectile as in claim 1, further comprising an explosive charge configured for creating an explosion sufficient to cause said elemental material to oxidize to produce the thermal event. 16. A projectile for creating a thermal event, comprising: a bullet including an elemental material having a purity of at least 75%; and a coating material capable of preventing oxidation of said elemental material, wherein at least 90% of said elemental material oxidizes within 10 seconds of removal of said coating material to produce a rapid thermal event. 17. The projectile as in claim 16, further comprising an oxidizing agent mixed with said elemental material and said coating material and isolated from said elemental material by said coating material, wherein said oxidizing agent is capable of reacting with said elemental material to result in the rapid thermal event; an explosive charge configured for creating an explosion sufficient to induce the oxidation of said elemental material and said oxidizing agent; and a detonator operatively connected with said explosive charge for igniting said explosive charge. 18. The projectile as in claim 17, wherein said elemental material, said coating material and said oxidizing agent define a longitudinal bore, and wherein said explosive charge and said detonator are located in said longitudinal bore. 19. A projectile for creating a thermal event, comprising: a bullet including an elemental material having a purity of at least 75% wherein at least 90% of said elemental material oxidizes within 10 seconds of exposure to oxygen to produce a thermal event. 20. The projectile as in claim 19, further comprising a coating material capable of preventing oxidation of said elemental material. 21. The projectile as in claim 19, further comprising an oxidizing agent capable of reacting with said elemental material so as to cause oxidation of said elemental material to result in the thermal event. 22. The projectile as in claim 19, wherein said elemental material is non-passivated.
