For non-native tree species with an origin outside of Europe a detailed compilation of enemy species including the severity of their attack is lacking up to now. We collected information on native and non-native species attacking non-native trees, i.e. type, extent and time of first observation of d ...

Fractal image feature vectors with applications in fractography
Hynek Lauschmann, Petr Bednařík, Zuzana Sekerešová, Michal Beneš
Izvirni znanstveni članek
Oznake:
The morphology of fatigue fracture surface (caused by constant cycle loading) is strictly related to crack growth rate. This relation may be expressed, among other methods, by means of fractal analysis. Fractal dimension as a single numerical value is not sufficient. Two types of fractal feature vec ...

Influence of aluminium-alloy remelting on the structure and mechanical properties
Nikol Špirutová, Michal Cagala, Marek Břuska, Petr Lichý, Jaroslav Beňo
Strokovni članek
Oznake: aluminium alloys;metallographic analysis;microstructures;thermomechanical properties;remelting;mechanical properties;
The aim of this work was to assess the repeated-remelting influence upon the mechanical properties, thermomechanical properties, chemical composition and structure changes of the selected material. An Al-Cu-type aluminum alloy was chosen on the basis of the ever increasing experiments with non-ferro ...

Studies on structural, mechanical and erosive wear properties of ZA-27 alloy-based micro-nanocomposites
Aleksandar Vencl, Mara Kandeva, Elena Zadorozhnaya, Petr Svoboda, Michal Michalec, Aleksandar Milivojević, Uroš Trdan
Izvirni znanstveni članek
Oznake: ZA-27 alloy;micro-nanocomposites;compocasting;microstructures;hardness;erosive wear;
Metal matrix nanocomposites represent a relatively new class of material, which is still being extensively investigated. Most of the studies, however, are devoted to aluminium- or magnesium-based nanocomposites. A limited number of studies focus on zinc alloy base nanocomposites, with fewer still co ...

Evaluation of steel desulphurization in the ladle during the utilization of briquetting fluxing agents for slags
Ladislav Socha, Jiří Bažan, Karel Gryc, Jan Morávka, Michal Pivko, Petr Styrnal, Václav Pilka, Zbygněv Piegza, Karel Michalek, Markéta Tkadlečková
Strokovni članek
Oznake: steel desulphurization;slag;fluxing agent;corundum;secondary metallurgy;steel;
This paper presents the experience obtained from plant experiments specialized in the usage of three types of fluxing agents for slags based on Al[sub]{2}O[sub]3. Proper experiments took place during the steel treatment by secondary metallurgy. The objective of the plant experiments was to assess th ...
