Patent number: 9016363Abstract: A frustoconical member includes a metal composite that has a cellular nanomatrix comprising a metallic nanomatrix material; a metal matrix disposed in the cellular nanomatrix; and a first frustoconical portion. A process of making the frustoconical member includes 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 frustoconical member having a tapered portion on an outer surface of the frustoconical member. The frustoconical member can be used by contacting a frustoconical portion of the frustoconical member to a tapered surface of an article; applying pressure to the frustoconical member; urging the frustoconical member in a direction relative to the article to expand a radial dimension of the article; and contacting the frustoconical member with a fluid to disintegrate the frustoconical member.Type: GrantFiled: May 8, 2012Date of Patent: April 28, 2015Assignee: Baker Hughes IncorporatedInventors: Zhiyue Xu, YingQing Xu, Gregory Lee Hern, Bennett M.
