Acicular ferrite (AF) is the most important microstructural constituent to achieve high toughness at low temperatures in weld metal of steels. This is due to the relatively small grain size and large misorientation angles. AF is known to form at non-

Equinor owns and operates a fleet of floating installations on the Norwegian Continental Shelf (NCS). As the installations are getting older, the importance of knowing the actual condition of the mooring systems has increased, and continuous mooring

Ultra-high temperature geothermal wells (>450 °C) have a large potential for increased energy yield as compared to conventional high-temperature geothermal wells (200-300 °C), but several research challenges must be resolved before robust operation

Material Design & Processing Communications
In the present investigation the aptness of the HYB process for butt welding of 4mm AA6082-T6 profiles is evaluated and benchmarked against one gas metal arc (GMA) weld and one friction stir (FS) weld, representing best practice for both methods. The

Duplex stainless steel has been used on subsea facilities since the mid 80-ties. The experiences with these materials have been relative good and only a few failures have been reported. However, BP and Shell experience some serious cracking of duplex

In this study, the effect of sigma-phase precipitation in duplex stainless steel (grade 2205) pipe fittings collected from top-side process systems offshore was investigated under realistic loading conditions. This was done by conducting quasi-static

Pipe fittings in duplex stainless steel (grade 2205) are used both top-side and subsea by the oil industry offshore. Precipitation processes during heat treatment of such fittings may result in various detrimental intermetallic phases and carbides. A

The deformation-induced martensite variant selection in a supermartensitic stainless steel (SMSS) has been examined in the temperature range from −60 °C to 150 °C, using in-situ tensile testing in combination with electron backscatter diffraction

Recent year's equipment design has enabled the combination of in situ deformation tests with near real time electron backscatter diffraction (EBSD) mapping of the microstructure evolution in the scanning electron microscope (SEM). The present work in
