A dissolvable tool includes, a body with a surface having at least one perforation therethrough, the at least one perforation being dimensioned to control a rate of intrusion of an environment reactive with at least a portion of the dissolvable tool located below the surface.
1. A dissolvable tool comprising a body with a surface having at least one perforation therethrough, the at least one perforation being dimensioned to control a rate of intrusion of an environment reactive with at least a portion of the dissolvable tool located below the surface the body being made
1. A dissolvable tool comprising a body with a surface having at least one perforation therethrough, the at least one perforation being dimensioned to control a rate of intrusion of an environment reactive with at least a portion of the dissolvable tool located below the surface the body being made of a powder metal compact, comprising: a substantially-continuous, cellular nanomatrix comprising a nanomatrix material;a plurality of dispersed particles comprising a particle core material that comprises Mg, Al, Zn or Mn, or a combination thereof, dispersed in the cellular nanomatrix; anda solid-state bond layer extending throughout the cellular nanomatrix between the dispersed particles. 2. The dissolvable tool of claim 1, wherein the body defines a ball. 3. The dissolvable tool of claim 1, wherein a cross sectional area of the at least one perforation is selected to control the rate of intrusion of the environment. 4. The dissolvable tool of claim 1, wherein a depth of the at least one perforation is selected to control the rate of intrusion of the environment. 5. The dissolvable tool of claim 1, wherein the at least one perforation is dimensioned to control surface area of the dissolvable tool exposed to the environment. 6. The dissolvable tool of claim 1, wherein the environment includes a chemical. 7. The dissolvable tool of claim 1, wherein the environment includes brine. 8. The dissolvable tool of claim 1, wherein the environment includes changes in temperature and pressure. 9. The dissolvable tool of claim 1, wherein the body includes a shell that defines the surface being made of a first material and the shell surrounds a core made of a second material. 10. The dissolvable tool of claim 9, wherein the shell is configured to fracture under loads experienced during use when not supported by the core. 11. The dissolvable tool of claim 9, wherein the second material is more reactive to the environment than the first material. 12. The dissolvable tool of claim 9, wherein the core provides structural support to the shell that reduces as the core reacts with the environment. 13. The dissolvable tool of claim 1, further comprising at least one plug positioned within the at least one perforation. 14. The dissolvable tool of claim 13, wherein the at least one plug is made of a different material than a balance of the body. 15. The dissolvable tool of claim 13, wherein the at least one plug is porous. 16. The dissolvable tool of claim 1, wherein the dispersed particles comprise Mg—Zn, Mg—Zn, Mg—Al, Mg—Mn, Mg—Zn—Y, Mg—Al—Si or Mg—Al—Zn. 17. The dissolvable tool of claim 1, wherein the dispersed particles have an average particle size of about 5 μm to about 300 μm. 18. The dissolvable tool of claim 1. wherein the dispersed particles have an equiaxed particle shape. 19. The dissolvable tool of claim 1, wherein the nanomatrix material comprises Al, Zn, Mn, Mg, Mo, W, Cu, Fe, Si, Ca, Co, Ta, Re or Ni, or an oxide, carbide or nitride thereof, or a combination of any of the aforementioned materials, and wherein the nanomatrix material has a chemical composition and the particle core material has a chemical composition that is different than the chemical composition of the nanomatrix material. 20. The dissolvable tool of claim 1, wherein the cellular nanomatrix has an average thickness of about 50 nm to about 5000 nm.
