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

https://www.sintef.no/publikasjoner/publikasjon/?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.

https://www.sintef.no/publikasjoner/publikasjon/?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...

Hydrogen Embrittlement at the Interface of Clad Steel Pipes – Fracture Mechanical Testing and FE Simulations

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1397243

The presence of a Ni-interlayer between clad and pipeline steel was found to reduced the fracture initiation toughness with 44 % for testing in air, while it raised the fracture initiation toughness with 216 % for testing under CP. • Fracture mechanical testing of the weld heat-affected zone clad in...

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

https://www.sintef.no/publikasjoner/publikasjon/?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 ...

Effect of crystal orientation and texture on fatigue crack evolution in high strength steel welds

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1248862

In the present study, electron backscattered diffraction is used to analyze the fatigue crack evolution in a high strength steel weld that was loaded cyclically in the plastic regime. Three prominent regions of a fatigue crack are investigated separately: crack tip, crack trajectory and crack initia...
