Evaluation of environment-assisted cracking susceptibility of a grade X100 pipeline steel
Susceptibility of as-received grade X100 steel was compared to that of simulated and seam-weld heat-affected zone microstructures by slow strain rate testing in a sodium hydrogen carbonate-sodium carbonate solution at 75 degrees C over a potential range ...

Analysis on Microstructure and Deformation Mechanics of X100 Linepipe Steel
29th International Conference on Ocean, Offshore and Arctic Engineering: Volume 6, 2010 In present paper, mechanical tests have been conducted on WT20.6mm×OD1016mm diameter Grade 690 linepipe. Microstructure is studied by means of OM, SEM, EBSD and TEM analysis. It is founded that the morphology of X100 steel consists mainly of fine acicular ferrite with little lath-shaped homogeneously distributed polygonal ferrite and very fine M/A ...

Ductile failure of X100 pipeline steel – Experiments and fractography
Materials & Design, 2013Abstract Ductile failure of X100 pipeline steel is studied. In order to study the effect of anisotropy, triaxiality factor and Lode angle on the failure, a series of specimens with different geometries are tested. Measurements of deformation in three dimensions are done to check the variation of elongation and lateral deformations during loading ...

Influence of Strain Aging on the Microstructure-Property of an X100 Pipeline Steel
Materials Science Forum, 2010 The influence of strain aging on the microstructure-property characterization of an X100 pipeline steel was investigated by means of a thermal simulation technique, microscopic analysis method and mechanical properties testing. The experimental steel was prestrained in the tension at 6 pct and then was baked at 150oC, 200oC, 250oC and 300oC for 60 ...

Static strain aging behavior of an X100 pipeline steel
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2012Abstract The effect of static strain aging on the microstructure and mechanical properties of an industrially produced X100 pipeline steel was investigated. It was found that strain aging plays an important role in the tensile property and features of stress–strain curves, with the increase of either pre-strain or aging temperature, the strength ...
