1. Welds in the lean duplex stainless steel LDX 2101 : effect of microstructure and weld oxides on corrosion properties
Abstract : Duplex stainless steels are a very attractive alternative to austenitic grades due to their higher strength and good corrosion performance. The austenitic grades can often be welded autogenously, while the duplex grades normally require addition of filler metal. READ MORE

2. Microstructure and properties of welds in the lean duplex stainless steel LDX 2101
Abstract : 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. READ MORE

3. Initiation and Repassivation of Pits on Austenitic Stainless Steel
Abstract : Stainless steels can be damaged by pitting corrosion in presence of aggressive anions, such as halide ions. The aim of this work was to study different aspects on initiation and repassivation of pits on austenitic stainless steel in chloride solutions at ambient temperature. READ MORE

4. Investigations of the corrosion resistances of magnetron sputtered multicomponent materials : A study on high entropy alloys, high entropy sublattice ceramics, and metallic glasses
Abstract : The corrosion resistances of sputter deposited AlCrNbYZrN, CrNbTiTaWC and TaNiSiC alloys were assessed in acidic and alkaline environments. Compositionally complex alloying strategies, and whether they produced coatings with superior corrosion resistances, were explored. READ MORE

5. Influence of multiple welding cycles on microstructure and corrosion resistance of a super duplex stainless steel
Abstract : Super duplex stainless steel (SDSS) has found a wide use in demanding applications such as offshore, chemical and petrochemical industries thanks to its excellent combination of mechanical properties and corrosion resistance. Welding of SDSS, however, is associated with the risk of precipitation of secondary phases and formation of excessive amounts of ferrite in the weld metal and heat affected zone. READ MORE
