Simulation of hydrogen diffusion in welded joint of X80 pipeline steel
Journal of Central South University, 2014Hydrogen diffusion coefficients of different regions in the welded joint of X80 pipeline steel were measured using the electro-chemical permeation technique. Using ABAQUS software, hydrogen diffusion in X80 pipeline steel welded joint was studied in consideration of the inhomogeneity of the welding zone, and temperature-dependent thermo-physical and ...

Micro-Behavior of Inclusions in X80 Pipeline Steel under Tensile Loading
Applied Mechanics and Materials, 2012Specially designed SEM in-situ tensile tests have been conducted to trace the entire process of crack initiation and propagation induced by inclusions in X80 pipeline steel. The main inclusions are complex oxides containing aluminum, calcium and magnesium with round or oval shape, and their sizes are in the range of 3~20μm.

Study on AC Corrosion on Cathodically Protected Pipeline of X80 Steel
CORROSION 2014, 2014Abstract Alternating current (AC) induced-corrosion on cathodically protected pipeline of X80 steel was studied by electrochemical impedance spectra (EIS). Experiments show that: EIS curves contain two time constants which represent high-frequency capacitance arc and low-frequency inductive loop, respectively.
