||Hydrogen Embrittlement of High Strength Nickel-based Alloys in HP HT Applications
||Ramgopal Thodla, Brandon Rollins
|On-Site Speaker (Planned)
High strength nickel based alloys are currently being considered for use in high pressure high temperature applications in O&G. While high strength nickel based alloys possess excellent corrosion resistance at elevated temperatures, they are susceptible to hydrogen embrittlement at low temperatures. The FCGR and hydrogen cracking of two high strength nickel based alloys in seawater under cathodic protection will be presented. The role of frequency and K on the FCGR behavior will be presented. The role of different tests methods on assessing the hydrogen cracking behavior of high strength nickel based alloys will also be discussed. The effect of strain rate on the SSR behavior of 718 will be presented. The role of K-rate on the fracture toughness behavior has been investigated and it's influence on the measured threshold will be presented.
