1. Factors Influencing the Formation of Shrinkage Porosity in Grey Cast Iron
Sammanfattning : The presence of shrinkage defects is of major concern in the production of grey iron castings. This type of defect can penetrate through the casting as a three-dimensional network. LÄS MER

3. Influence of multiple welding cycles on microstructure and corrosion resistance of a super duplex stainless steel
Sammanfattning : 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. LÄS MER
4. Investigation and modelling of friction stir welded copper canisters
Sammanfattning : This work has been focused on characterisation of FSW joints, and modelling of the process, both analytically and numerically. The Swedish model for final deposit of nuclear fuel waste is based on copper canisters as a corrosion barrier with an inner pressure holding insert of cast iron. LÄS MER
