Proc. ASME. IPC2008, 2008 7th International Pipeline Conference, Volume 3, 301-306, September 29–October 3, 2008
Publisher: American Society of Mechanical Engineers
Paper No: IPC2008-64398
... 10 07 2009 The welding processes used to produce microalloyed steel pipe can result in mechanical property changes in the heat affected zone (HAZ) regions of seam and double joint (circumferential) welds. HAZ properties are controlled primarily by the microstructures resulting from...

Paper No: IPC2008-64643
... 10 07 2009 The mechanical properties of microalloyed steels used in pipelines are strongly affected by microstructure. In this paper, X-ray diffraction (Rietveld method) was used to quantify the microstructure — specifically domain size, microstrain and preferred orientation — for four...
