16. The Atmospheric Corrosion of Magnesium Alloys : Influence of Microstructure and Environments
Sammanfattning : The low density and high specific strength of magnesium alloys have created a great deal of interest in the use of these alloys in the automotive and aerospace industries and in portable electronics. All of these industries deal with applications in which weight is extremely important. LÄS MER
17. Interaction between the alloying content, cast structure and forging process for large ingots
Sammanfattning : .... LÄS MER
18. Rapid solidification behaviour of Fe and Al based alloys
Sammanfattning : Rapid solidification experiment on Fe-Cr-Mo-Mn-Si-C alloy was performed to investigate metastable phases formed during the solidification. A wide range of cooling rate was used to analyse the sample from melt spinning technique (~107 K/s) to water quenching method (~102 K/s). LÄS MER
19. A Study of EAF Austenitic and Duplex Stainless Steelmaking Slags Characteristics
Sammanfattning : The high temperature microstructure of the solid phases within the electric arc furnace (EAF) slag has a large effect on the process features such as foamability of the slag, chromium recovery, consumption of the ferroalloys and the wear rate of the refractory. The knowledge of the microstructural and compositional evolution of the slag phases during the EAF process stages is necessary for a good slag praxis. LÄS MER
20. Thermodynamic Aspects on Inclusion Composition and Oxygen Activity during Ladle Treatment
Sammanfattning : Two industrial studies and one set of lab scale trials have been done. In addition, a theoretical study has been done. The main focus has been on non metallic inclusion composition during the ladle refining operation in industrial steel production. Sampling has been done together with careful inclusion determination.
