Assessment of the potential of hydrogen plasma charging as compared to conventional electrochemical hydrogen charging on dual phase steel.
Depover, Tom; Hajilou, Tarlan; Wan, Di; Wang, Dong; Barnoush, Afrooz; Verbeken, Kim (Journal article; Peer reviewed, 2019)The present study evaluates the hydrogen induced damage by in-situ hydrogen plasma charging in dual phase (DP) steel. Cold deformation of 15% is applied on the material to change microstructural defects, such as dislocation ... -
The effect of hydrogen on the crack initiation site of TRIP-assisted steels during in-situ hydrogen plasma micro-tensile testing: Leading to an improved ductility?
Depover, Tom; Wan, Di; Wang, Dong; Barnoush, Afrooz; Verbeken, Kim (Peer reviewed; Journal article, 2020)The hydrogen induced damage and crack initiation in transformation induced plasticity (TRIP) steel is considered in the present work by micro tensile testing and subsequent microstructural assessment. Hydrogen characteristics ... -
Evaluation of microstructural and environmental effects on the hydrogen uptake and desorption in high-strength carbon steels: A thermal desorption spectroscopy study
Karimi, Shabnam; Taji, Iman; Palencsar, Simona; Dugstad, Arne; Hajilou, Tarlan; Barnoush, Afrooz; Verbeken, Kim; Johnsen, Roy; Depover, Tom (Peer reviewed; Journal article, 2023)The hydrogen uptake in three high-strength carbon steels is studied after exposure to three different environments: an aqueous solution with CO2 bubbling, CO2/H2S bubbling, and cathodic charging without external gassing. ... -
Investigation of corrosion behavior, hydrogen uptake, and hydrogen embrittlement of armor wires made from carbon steels
Karimi, Shabnam (Doctoral theses at NTNU;2023:242, Doctoral thesis, 2023)The effect of cementite morphology on corrosion layer formation, hydrogen uptake, crack initiation, and growth in the presence of hydrogen was investigated in carbon steels which are used to fabricate tensile armor wires ... -
Role of cementite morphology on corrosion layer formation of high-strength carbon steels in sweet and sour environments
Karimi, Shabnam; Taji, Iman; Hajilou, Tarlan; Palencsar, Simona; Dugstad, Arne; Barnoush, Afrooz; Verbeken, Kim; Depover, Tom; Johnsen, Roy (Peer reviewed; Journal article, 2023)The effect of cementite morphology on the corrosion layer formation of four high-strength carbon steels was studied in an aqueous solution containing CO2 and CO2/H2S. The linear polarization resistance and weight loss data ...
