1. Laser cladded steel - microstructures and mechanical properties of relevance for railway applications
Sammanfattning : Owing to increased requirements like increased axle load for railway wheels and rails, new material have to be employed. However, these requirements are mostly surface related, which makes it appropriate to change only the surface layer while keeping the bulk unchanged. LÄS MER
2. Microstructure and properties of welds in the lean duplex stainless steel LDX 2101
Sammanfattning : 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. LÄS MER
3. Welds in the lean duplex stainless steel LDX 2101 : effect of microstructure and weld oxides on corrosion properties
Sammanfattning : 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. LÄS MER
4. The Precipitation and Deformation Behaviour of Superaustenitic Stainless Steel
Sammanfattning : The present study concerns the precipitation behaviour and the deformation characteristics of a superaustenitic stainless steel with composition Fe-24Cr-22Ni-7.3Mo-0.5N (wt%). Regarding precipitation, also materials with Mo partially replaced by W have been studied. LÄS MER
5. Weldability of Precipitation Hardening Superalloys – Influence of Microstructure
Sammanfattning : Superalloys and in particular the precipitation hardened Ni-based superalloys havealways been used extensively in the hot sections of jet engines. Large hot structuralengine components with complex geometry have preferably been cast as single piececomponents since the large scale vacuum investment casting process becameavailable about fifty years ago.
