Weldability and hydrogen relationships in super duplex stainless steel.
As the microstructure of commercial duplex stainless steels consists of approximately 50% austenite and 50% ferrite, the response of these two phases to hydrogen is of interest to the users of these materials. A study has been made of the hydrogen cracking behaviour in welded super duplex stainless …

Investigation into the transformation products of CD3MN cast duplex stainless steel
<p>The transformation products for CD3MN cast duplex stainless steel (DSS) were investigated between the temperatures of 600 to 9500C. The primary research evaluated the kinetics of sigma ([Sigma]) phase formation by developing the time-temperature-transformation diagram for CD3MN and comparing …

The low temperature fracture behaviour of the super duplex stainless steel Zeron 100
… of fracture in an austenitic/ferritic super-duplex stainless steel (Zeron 100) have been studied for a range of product forms, including cross-rolled plate, conventional (ingot) route and powder route extruded pipe, hot isostatically pressed (HIP'd) powder, and weldments produced using both …

Fatigue properties of dissimilar metal laser welded lap joints.
This work involves laser welding austenitic and duplex stainless steel to zinc-coated mild steel, more specifically 1.2mm V1437, which is a Volvo Truck Coiporation rephosphorised mild steel. The work investigates both tensile and lap shear properties of similar and dissimilar metal laser welded …

Corrosion fatigue initiation in stainless steels : The scanning reference electrode technique.
… of damage by corrosion fatigue in austenitic and duplex stainless steel were studied using a novel scanning reference electrode technique (SRET). Emphasis was made on the role played by corrosion pits, which can act as stress concentrators and promote fatigue crack nucleation. SRET measurements …

Empirical Multiphase Model for Strength Evolution of High-Chromium Steel Alloys
Duplex stainless steel 2205 (DSS2205) exhibits complex non-monotonic strength evolution during thermal ageing at elevated temperatures, limiting predictive capability for long-term component life assessment. This dissertation develops and validates the METALS (Microstructure Evolution and Thermal …
