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. Localized corrosion of stainless steels in chlorine dioxide bleach filtrate solutions
Abstract : Stainless steels are extensively used in pulp bleach plantsbecause of their high corrosion resistance. However, alsostainless steels might suffer from corrosion and in bleachplants this is a problem. READ MORE

4. Microstructure and Inclusion Characteristics in Steels with Ti-oxide and TiN Additions
Abstract : Non-metallic inclusions in steels are generally considered to be detrimental for mechanical properties. However, it has been recognized that certain inclusions, such as Ti-oxide and TiN, can serve as potent nucleation sites for the formation of intragranular ferrite (IGF) in low-alloy steels. READ MORE

5. Materials and Coatings for Superheater Tubes in Biomass- and Waste-fired Boilers
Abstract : Combustion of biomass and waste fuels has strong potential as an alternative renewable energy source for meeting the increasing global energy demand, while reducing the net release of CO2 into the atmosphere. The combustion of biomass and waste releases flue gases that contain high amount of alkali salts and water vapour, which drive the corrosion of metallic boiler components. READ MORE
