Abstract: In recent years, nanoparticles have high importance in various areas such as biomedical, environmental or pharmaceutical applications due to their chemical and physical properties. In all these applications, maintaining control over the particle size and shape is of high significance due to their size and shape-dependent properties. [..] Read more

Abstract: Carbon nanotubes (CNTs) are a popular sample for various nanotechnology studies. However, they are very difficult to synthesize en masse. [..] Read more

Abstract: As primary resources become more and more complex in their chemical composition and some places poor in their valuable metals in the ore secondary sources like slag phases from the production processes get in the focus of the metal industry. Currently about 70% of copper slag remains is ineffectively utilized. [..] Read more

Abstract: The paper is devoted to a discussion of the results obtained by the simultaneous use of three methods of thermal analysis in three different specialized devices with the aim to precise solidus and liquidus temperatures. The low carbon as-cast steel (130 mm round format) from Continuous Casting Machine No. [..] Read more

Abstract: CALPHAD-based calculations, for quite some time now, have been very useful and convenient way to obtain data needed for modelling of solidification process. Among scientists, interested in and working on the topic, knowledge of existence of software for thermodynamic calculations is widely spread, but at the same time its usage is limited. [..] Read more

Abstract: In this article, the intensity of mold metal reactions between ceramic shell and magnesium alloy AZ91E is studied. The two possible protective gasses used for melt protection are studied - SF6 (sulphur hexafluoride) and 3M NOVEC 612. [..] Read more

Abstract: During the production of high carbon ferromanganese, the feed undergoes different stages of reduction. Three main zones were assumed instead of traditional four. [..] Read more

Abstract: The submitted article deals with the study of casting and solidification of a 12 t ingot made of structural steel 42CrMo4 using numerical simulations in the THERCAST® and MAGMASOFT® software. The possibilities of each individual software in filling and solidification of steel were assessed, including the prediction of ingot defects such as porosity, shrinkage cavities or shrinkage porosities; the proportion of liquid phase, segregation of selected elements and solidification time were also monitored.. [..] Read more

Abstract: Electrical steel sheet is an important material in the manufacture of various parts of electrical devices with high magnetic properties. The need to form the desired properties of the metal makes special demands on the organization of the production technology for both hot-rolled and cold-rolled sheets. [..] Read more
