연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The expandable apparatus of claim 1, wherein the expandable apparatus comprises at least one of an expandable reamer apparatus and an expandable stabilizer apparatus. 3. The expandable apparatus of claim 1, wherein the expandable apparatus comprises a seat for receiving the triggering element. 4. The expandable apparatus of claim 3, wherein the seat comprises an opening at a downhole end thereof enabling the triggering element, in an at least partially corroded condition, to pass through the seat and exit the expandable apparatus through the longitudinal bore. 5. The expandable apparatus of claim 1, further comprising: a push sleeve disposed within the longitudinal bore of the tubular body and coupled to the at least one member, the push sleeve configured to move the at least one member from the retracted position to the extended position responsive to a flow rate of drilling fluid passing through the longitudinal bore; anda traveling sleeve positioned within the longitudinal bore of the tubular body and partially within the push sleeve, the traveling sleeve comprising a seat for receiving and securing the triggering element. 6. The expandable apparatus of claim 1, wherein the composite material of the body has a compressive yield strength of at least about 250 MPa. 7. The expandable apparatus of claim 1, wherein the discontinuous metallic phase comprises nanoparticles of the metal or metal alloy. 8. The expandable apparatus of claim 1, wherein the discontinuous metallic phase comprises commercially pure magnesium or a magnesium alloy. 9. The expandable apparatus of claim 1, wherein the corrodible matrix phase further comprises at least one of oxygen, magnesium oxide, aluminum oxide, and nickel oxide. 10. The expandable apparatus of claim 1, wherein the corrodible matrix phase is configured to corrode in at least one of a brine solution and an acidic solution. 11. The expandable apparatus of claim 10, wherein the triggering element comprises: a shell defining an outer surface of the triggering element comprising a first material;a core comprising a second material being substantially surrounded by the shell, wherein the second material comprises the composite material and wherein the first material is formed from a relatively non-corrodible material as compared to the composite material; andat least one perforation formed in the triggering element, the at least one perforation extending from the outer surface of the triggering element through the first material of the shell and into the second material of the core by at least some depth and being dimensioned to control a rate of intrusion of the at least one of the brine solution and the acidic solution into at least a portion of the triggering element. 12. The expandable apparatus of claim 1, wherein the triggering element comprises: at least two or more portions formed from a relatively non-corrodible material as compared to the composite material of the triggering element; andan adherent corrodible material comprising the composite material binding the at least two parts of the ball together. 13. The expandable apparatus of claim 1, wherein the triggering element comprises at least one stress riser extending through an outer surface of the triggering element and into the triggering element, the at least one stress riser configured to concentrate stress in order to accelerate structural degradation of the triggering element. 14. The expandable apparatus of claim 1, wherein the triggering element comprises a shell defining an outer surface of the triggering element comprising a first material and a core comprising a second material being substantially surrounded by the shell, at least one stress riser extending through the outer surface of the triggering element and into the shell of the triggering element, the at least one stress riser configured to concentrate stress in order to accelerate structural degradation of the triggering element, wherein the second material comprises the composite material and wherein the first material is formed from a relatively non-corrodible material as compared to the composite material. 15.
