Influence of modifying methods on quality of eutectic and hypereutectic silumine for diesel engine pistons
(Maney Publishing, Leeds, 2013)
The results of the investigation of the influence of different modifiers (sodium, phosphorus, antimony and strontium) on the quality of AlSi12CuMgNi and AlSi18CuMgNi alloys, which are used for the production of pistons, ...
Application of chromite in the production of refractory coatings
(Verlag Schmidt GmbH, 2013)
This work investigated the possibility of developing new chromite-based refractory coatings for hot metal casting applications. The coating composition and rheological properties were optimized by careful choice of binding ...
What to expect from heavy clay?
(Elsevier Sci Ltd, Oxford, 2013)
The need of testing the quality of brickclay arises in all brick factories, with the opening of new deposits. The analyses are both time and economically consuming, so the aim of this study was to shorten the procedure ...
Assessment of the effect of pitting corrosion on fatigue crack initiation in hydro turbine shaft
(Trans Tech Publications Ltd, 2013)
Energy efficiency is a key issue worldwide, and not confined solely to the realm of engineers. Past failures of mechanical power system components must be examined carefully in order to minimise future occurrences and ...
Geopolimeri na bazi alkalno aktiviranog elektrofilterskog pepela kao novo vezivo u betonu / Alkali activated fly ash geopolymers as a new binder in concrete
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2013)
U skladu sa rastućom brigom za zaštitu životne sredine i potrebom razvoja održivog građevinarstva, javlja se i veće interesovanje za istraživanja u oblasti novih materijala, koji će koristiti otpadne sirovine i imati manji ...
Evaluation of Lignite Fly Ash for Utilization as Component in Construction Materials
(Taylor & Francis Inc, Philadelphia, 2013)
Utilization potential of fly ash, as the main residue in the lignite coal combustion in Serbian power plants, was investigated in present study. High production of fly ash represents extreme hazard for environment. Question ...
High-temperature concrete binders based on fly ash
(Revista Romana de Materiale/ Romanian Journal of Materials, 2013)
High-temperature concrete binders in which fly ash, as environmentally harmful secondary raw material, is combined with masonry and refractory cement is a new option for reapplication of this coal combustion by-product. ...
Prediction and fuzzy synthetic optimization of process parameters in heavy clay brick production
(Elsevier Sci Ltd, Oxford, 2013)
Many factors influence final clay brick properties, since the raw materials used are highly heterogeneous. Statistical analysis is rarely used, according to literature, but it would improve understanding of the overall ...
Life extension of gears flank surfaces regenerated by hard facing
(Editura Stiintifica Fmr, Bucharest, 2013)
This paper contains the results of experimental analysis of fatigue endurance of used steel teeth regenerated by hard facing. The cylindrical spur gears were tested and compared with the newly made ones, oiler being ...
Methodological approach to recovery of the cracks on the turbine-shaft at hydroelectric power plant djerdap II
(Springer Netherlands, 2013)
In present paper, the methodological approach to analysis of the causes of failures and recovery of the damages has been presented using the example of the damage of the turbine-shafts construction. This approach can be ...
