A seal includes a metal composite that has a cellular nanomatrix that includes a metallic nanomatrix material, a metal matrix disposed in the cellular nanomatrix, and a disintegration agent; an inner sealing surface; and an outer sealing surface disposed radially from the inner sealing surface. The seal can be prepared by combining a metal matrix powder, a disintegration agent, and metal nanomatrix material to form a composition; compacting the composition to form a compacted composition; sintering the compacted composition; and pressing the sintered composition to form the seal.
1. A seal comprising: a metal composite including: a cellular nanomatrix comprising a metallic nanomatrix material;a metal matrix disposed in the cellular nanomatrix; anda disintegration agent;a first sealing surface; anda second sealing surface opposingly disposed from the first sealing surface, wh
