Essay

The hydrogen role in sulfide stress cracking (SSC) of low alloy rotor and pipeline steels and their weldments has been investigated. The role of mobile hydrogen under active-to-passive transition in this process has been established. The methods of improving stress-corrosion durability have been developed. Electrochemical, metallographic, fractographic, analytical, and thermodynamic studies have conducted. Effects of polarization and of hydrogen permeation on SSC of low alloy steels and residual hydrogen concentration have been studied. Field of application - oil/gas production and power generation industries
