11. Multiscale material modeling of duplex stainless steel
Sammanfattning : .... LÄS MER
12. The Influence of Composition and Hot Processes on Heat Affected Zone and Weld Metal Behavior and Mechnacal Properties of Ti Grade 5 and Stainless Steel
Sammanfattning : This thesis discusses on results of experiments carried outwith austenitic, duplex and super duplex stainless steels andTi-6Al-4V. In these it has been seen that the heat cycle duringwelding or weld simulation has a great effect on the propertiesof thematerials. LÄS MER
13. Thin-Film Coated Steel Foils as Interconnects for Solid Oxide Fuel Cells (SOFC)
Sammanfattning : Solid Oxide Fuel Cells (SOFCs) are electrochemical energy conversion devices that have the potential to achieve high efficiencies while using a broad range of fuels. The advancement of the technology has however been hindered by a number of technical and economic barriers, one of which is the durability and cost of the bipolar plate or interconnect that connects individual cells in series to form a so-called ‘stack’.

14. Fracture toughness properties of duplex stainless steels
Sammanfattning : Good toughness properties in base and weld material enable the use of duplex stainless steels (DSS) in critical applications. DSS offer high strength compared to common austenitic stainless steels. LÄS MER
15. Super duplex stainless steels : Microstructure and propertiesof physically simulated base and weld metal
Sammanfattning : High-temperature processing and application of super duplex stainless steel(SDSS) are associated with the risk of changes in the ferrite/austenite balance and precipitation of secondary phases. This study was therefore aimed at improving knowledge about effects of thermal cycles on the microstructure and properties of SDSS base and weld metal. LÄS MER
