6. Phase separation in duplex stainless steel: characterization and mitigation
Sammanfattning : Duplex stainless steel (DSS) is a category of widely used stainlesssteel, which are strategically important in a variety of applications such asin the food industry, chemical engineering plants and nuclear power plants,due to their attractive combination of mechanical properties and corrosionresistance. However, these steel grades are sensitive to the so-called ‘475°Cembrittlement’, because of a phase separation (PS) phenomenon in theferrite phase, which decomposes into Fe-rich ferrite (α) and Cr-rich ferrite(α'), when exposed to temperatures within the miscibility gap.

8. Passivity & Breakdown of Super Duplex Stainless Steel : Studied with Electrochemical & Synchrotron Techniques
Sammanfattning : Super duplex stainless steel consists of two phases: austenite and ferrite, and is a highly corrosion resistant material, with a wide range of applications. The corrosion resistance of stainless steels is determined by the performance of a spontaneously formed thin Cr oxide rich film with a thickness of 1-3 nm. LÄS MER

10. Microstructure and properties of welds in the lean duplex stainless steel LDX 2101
Sammanfattning : Duplex stainless steels can be very attractive alternatives to austenitic grades due to their almost double strength at equal pitting corrosion resistance. When welding, the duplex alloys normally require addition of filler metal, while the commodity austenitic grades can often be welded autogenously. LÄS MER
