21. Experimental study of phase separation in Fe-Cr based alloys
Sammanfattning : Duplex stainless steels (DSSs) are important engineering materials due to their combination of good mechanical properties and corrosion resistance. However, as a consequence of their ferrite content, DSSs are sensitive to the so-called ‘475°C embrittlement’, which is induced by phase separation, namely, the ferrite decomposed into Fe-rich ferrite (α) and Cr-rich ferrite (α'), respectively.

22. Coated Ferritic Stainless Steels as Interconnects in Solid Oxide Fuel Cells - Material Development and Electrical Properties
Sammanfattning : Solid oxide fuel cells (SOFCs) are attracting increasing interest as devices with potentialuses in decentralized and clean electricity and heat production. Several challengeswith respect to materials have to be overcome to achieve efficiencies and life-spansthat are sufficient for long-term applications. LÄS MER
23. Studies of strain hardening, strain ageing and fatigue in ferritic steels in terms of dislocation mechanisms
Sammanfattning : .... LÄS MER
24. Corrosion of ferritic stainless steels used in solid oxide fuel cells - Investigation of novel coatings in single- and dual-atmosphere conditions
Sammanfattning : Solid Oxide Fuel Cells (SOFCs) are systems that convert chemical energy into electrical energy. Their high electrical efficiency and clean emissions (when H2 is used as fuel) make them a strong candidate for replacing conventional conversion systems, such as combustion engines. LÄS MER
25. Plastic Deformation of Duplex Stainless Steel
Sammanfattning : Duplex austenitic/ferritic stainless steels are increasingly used as an alternative to conventional austenitic grades. Main advantages of the duplex grades are good resistance to corrosion cracking and corrosion fatigue in environments that contain chloride. LÄS MER
