Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2011 Abstract The effect of welding thermal cycle simulation on the microstructure and mechanical properties of X90 pipeline steel was investigated by means of microstructure analysis, tensile- and Charpy impact-tests. At the heat input of 15 kJ/cm, the microstructure of coarse-grained heat affected zone is mainly composed of lath bainite and granular ...

Effect of Austenitic State on the Multi-phase Control in X90 Pipeline Steel with High Nb Content
Materials Today: Proceedings, 2015 Abstract This work focuses on the effects of different austenization temperatures on the continuous cooling transformation kinetics and the ultimate microstructures characteristics of 620 MPa grade (X90) pipeline steel. The results indicated that the austenitic state has significant influence on the diffusive transformation with the cooling rate of 1

Quantification of the temperature threshold of hydrogen embrittlement in X90 pipeline steel
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2021Abstract In the current research, the dependence of hydrogen embrittlement (HE) on the temperature in X90 steel is studied through experimental tests and molecular dynamics simulations. Slow strain rate tests (SSRT) were applied to X90 specimens in the air and the simulated groundwater solution (called NS4), respectively. The fracture morphologies of

PROPERTIES AND MICROSTRUCTURE OF THIRD GENERATION X90 PIPELINE STEEL
Jinshu Xuebao/Acta Metallurgica Sinica, 2013The mechanical properties and microstructure of the TG (third generation) X90 pipeline steels which have been industrially trial-produced were investigated. The results showed that the microstructure of the 18.4 mm thick X90 pipeline steels consist of quasi-polygonal ferrite, lath bainite and M/A (martenite/austenite) island.
