Cryptomelane (α-(K)MnO2 ) powders were synthesized by different methods leading to only slight differences in their bulk crystal structure and chemical composition, while the BET surface area and the crystallite size differed significantly. Their performance in the oxygen evolution reaction (OER) covered a wide range and their sequence of increasin...

V livarnah in industriji aluminija se sekundarne surovine uporablja za boljši izkoristek in večjo produktivnost procesa. V magistrskem delu smo preučili vpliv deleža krožne litine na kvaliteto AlSi9Cu3 ulitkov. Opazili smo vplive različnih deležev krožne litine na mehanske lastnosti, kot naprimer trdota in natezna trdnost. Sprva smo izvedli enostav...

High Temperature Materials and Processes
The cylindrical samples of TC4 titanium alloy prepared by spark plasma sintering (SPS) were compressed with hot deformation of 70% on the thermosimulation machine of Gleeble-1500. The temperature of the processes ranged from 850°C to 1,050°C, and the strain rates varied between 0.001 and 5 s−1. The relative density of the sintered and compressed sa...

Beton je zgodovinsko gledano eden najbolj pomembnih in uporabljenih materialov in ravno zaradi tega je njegovo propadanje zelo velik problem. Za njegovo preprečitev pa je potrebno razumeti različne vzroke propadanja betona. Največji delež k propadanju betona gre prepisati naravnim in kemijskim dejavnikom. Alkalno-karbonatna reakcija spada med kemij...

Cold metal transfer (CMT) technique is developed for lap joining of titanium (Ti) alloy to stainless steel (SS) with CuSi3 filler wire. The effect of welding speed on the microstructure and mechanical properties of Ti/SS lap joints is investigated. The results indicate that the wetting angle of the lap joints gradually increases and the weld width ...

The medium temperature reheating and two-stage cold rolling process were adopted to produce industrialized Grain-oriented silicon steel. Results showed there were three sections (surface layer, transition layer and central layer) along the thickness direction on hot rolled sheets. Surface layer was occupied by complete recrystallization grains with...
