Hydrogen embrittlement in structural steel welds – influence of varying the stress concentration

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1517622

Hydrogen Embrittlement (HE) has been a known phenomenon for several decades. Despite that, it still represents a critical problem for Carbon Manganese steel used in structural applications. For the particular case of subsea pipelines and their weldments, atomic hydrogen from the cathodic protection ...

A special notched tensile specimen to determine the flow stress-strain curve of hardening materials without applying the Bridgman correction

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1467315

Structural integrity assessment of weldments requires the input of flow stress-strain curve of each individual material zone. To cope with these challenges, a cylindrical cross weld tensile specimen with a notch located either in the weld metal, base metal or possibly heat affected zone has been pre...

Fracture toughness and hydrogen embrittlement susceptibility on the interface of clad steel pipes with and without a Ni-interlayer.

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1418078

The objective of the present work has been to study the fracture properties of the interface between clad and base material of two 316 L austenitic stainless steel - X60/X65 carbon steel hot roll bonded clad pipes; with and without a Ni-interlayer. Fracture mechanical tests were performed in air and...

Assessment of low temperature toughness in welding of extra low carbon steel for Arctic application

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1399758

For steel structures to be installed in the Arctic region, the risk of brittle fracture represents a primary concern due to the ductile to brittle usually transition taking place at sub-zero temperatures. Therefore, the present investigation addressed the heat affected zone and weld metal toughness ...
