Rare earth metals are used in semiconductors, solar cells and catalysts. This review focuses on the background of oxide metallurgy technologies, the chemical and physical properties of rare earth (RE) metals, the background of oxide metallurgy, the functions of RE metals in steelmaking, and the influences of RE metals on steel microstructures. Future prospects for RE metal applications in steel...

Carbon dioxide corrosion has been widely studied in the field and laboratory. It is recognized that flow regime and metallurgy are important factors that influence in-situ corrosion rates but there are relatively few documented case studies that are able to separate the individual contributions of corrosion, flow regime and metallurgy on the observed corrosion damage. This paper deals with fail...

The article presents the most common directions of changes in capital groups in the sector of metallurgy around the world and in Poland. During the observation of the restructuring activities in metallurgy the attention was turned to the integration of the capital groups, capital outsourcing and contract outsourcing, creation and the takeover of the dependent companies. The meaning of the capit...

K. Nowacki, P. Musiał, T. Lis Silesian University of Technology, Department of Metallurgy, Katowice, Poland Acoustic steel processing in an ingot mould may be the fi nal stage in the process of quality improvement of a steel ingot. The impact of radiation and cavitation pressure as well as the phenomena related to the acoustic wave being emitted and delivered to liquid steel aff ect various asp...

This paper discusses the influence of Particle Stimulated Nucleation (PSN) on the overall process of nucleation and subsequent grain growth in low carbon (LC) steels and proposes a global recrystallisation kinetics model based on fundamental physical metallurgy principles. The model takes into account the cementite content, which is dependent on the nominal carbon content, and the second phase ...

K. Janiszewski, B. Panic: Silesian University of Technology, Department of Metallurgy, Katowice, Poland Hitherto existing investigations concerning the ceramic fi lter use in the steel making processes have given good results. The obtained results of fi ltration have proved that this method may be used as an eff ective and cheap way of steel fi ltration from non-metallic inclusions. Placing fi ...

K. Janiszewski, Silesian University of Technology, Department of Metallurgy, Katowice, Poland. Hitherto existing investigations concerning the ceramic fi lter use in the steel making processes (both of laboratory and industrial scale) have given good results. The obtained results of fi ltration (in the laboratory) have proved that this method may be used as an eff ective and cheap way of steel ...
