Analysis of Marketing Mix Tools in ENRC Marketing AG
Kopecká, Kateřina ; Novák, Michal (advisor) ; Kincl, Tomáš (referee)
This thesis describes marketing mix of ENRC Marketing AG. History of marketing will be shortly mentioned as well as its general function at present. Marketing mix will be described as one of the basic parts of marketing plan. Actual status of that company will be analysed and in the practical part of the thesis new marketing mix, which should increase aluminium sales will be proposed.

Forms of aluminium in waters and ways of their removing
Tomášková, Hana ; Benešová, L.
The aluminium exists in various species in the environment. The toxicity of aluminium is not only determined by the total aluminium concentration, but also closely related to the aluminium species. Specific aluminium fraction have been analyzed from two drinking water reservoirs Pilská and Lázská in Czech Republic and also in treated water from these reservoirs.

MICROSTRUCTURE/PROPERTIES RELATIONSHIP IN ULTRAFINE GRAINED ALUMINIUM PROCESSED BY ECAP TACHNIQUE
Král, Petr ; Dvořák, Jiří ; Svoboda, Milan ; Sklenička, Václav
Experiments were conducted on pure ultrafine grained aluminium processed by severe plastic deformation using the equal ů channel angular pressing ů ECAP technique. By this technique bulk ultrafine grained material was prepared. The propertis of this material considerably differs from properties of material with standard grain size. It was found that microstructure of ultrafine grained aluminium after one pass by the ECAP die contains subgrains and these subgrains are changed by subsequent ECAP passes in grains separated by high angle grain boundaries. In this work special attention is given to the stability of microstructure and the relationship between microstructure and mechanical properties of ECAP material.

MECHANISMY CREEPOVÉ DEFORMACE U UTRAJEMNOZRNNÉHO HLINÍKU PŘIPRAVENÉHO METODOU ECAP
Dvořák, Jiří ; Sklenička, Václav ; Král, Petr
Extremely coarse-grained aluminium (99,99%) was subjected to severe plastic deformation (ECAP)for obtain an ultrafine-grained microstructure. Creep tensile and compression tests were conducted on such material and for comparison reasons also on coarse-grained aluminium. The results indicate an increased creep resistant of ultrafine-grained aluminium compared to its coarse-grained state. It was proposed, that creep of ultrafine-grained aluminium is probably control by the same creep mechanisms as coarse-grained one. However, the role of grain boundary sliding in creep considerably differs in both ECAP and coarse-grained materials
