Abstract:
A lightweight, selectively degradable composite material is disclosed. The composite material comprises a compacted powder mixture of a first powder, the first powder comprising first metal particles comprising Mg, Al, Mn, or Zn, or an alloy of any of the above, or a combination of any of the above, having a first particle oxidation potential, a second powder, the second powder comprising low-density ceramic, glass, cermet, intermetallic, metal, polymer, or inorganic compound second particles, and a third metal powder, the third metal powder comprising third metal particles having an oxidation potential that is different than the first particle oxidation potential. The compacted powder mixture has a microstructure comprising a matrix comprising the first metal particles, the second particles and third particles dispersed within the matrix, the third particles comprising a network of third particles extending throughout the matrix, the composite material having a density of about 3.5 g/cmor less.
