1. Recovery of iron and manganese values from metallurgical slags by the oxidation route
Sammanfattning : In the modern practice, a sustainable development strategy in a domain of wasteutilization is shifting its focus from a general completeness of recycling to a morespecific attention to efficiently utilize elements in the wastes. This is well-illustrated bythe steelmaking slag industries. LÄS MER
2. Effect of Microstructure on Mechanical Properties of High Strength Steel Weld Metalsn
Sammanfattning : The effects of variations in alloying content on the microstructure and mechanical properties of high strength steel weld metals have been studied. Based on neural network modelling, weld metals were produced using shielded metal arc welding with nickel at 7 or 9 wt. %, manganese at 2 or 0.5 wt. LÄS MER
3. Investigation of electrical and magnetic properties of nanoparticles and nanofibers with the aim to tailor material properties of nanocomposites
Sammanfattning : Nanocomposites are the subject of interest in this study which can be explained by the factum that using building blocks with dimensions in the nanosize range makes it possible to design and create new materials which can satisfy several functions at the same time for many applications. The applications of interest in this study belong to the microwave frequency region and for that reason a number of materials were investigated to define their microwave absorbing properties. LÄS MER
4. 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
5. On the mechanisms of structure formation in nodular cast iron
Sammanfattning : The mechanisms of structure formation in nodular cast ironhave been examined by experiments and by physical modelling. Byincorporation of models for nucleation and growth for allrelevant phases into a heat flow calculation. it is possible topredict the as-cast structure by computer simulation. LÄS MER
