Klasifikacija eksploatacijskih oštećenja čeličnih užadi / Classification of in-service damages of Steel wire ropes
(Institut za ispitivanje materijala, Beograd, 2007)
Radni vek čeličnih užadi je ograničen zbog promene njihovih svojstava tokom eksploatacije pod dejstvom radnih uslova i opterećenja. Redovan nadzor tokom eksploatacije omogućava kontrolu razvoja oštećenja i normalni proces ...
Influence of Mechanical Activation of a Cordierite –Based Filler on Sedimentation Stability of Lost Foam Refractory Coatings
(Science of Sintering, 2019)
For the development of the Lost Foam refractory coatings with controlled rheologic properties, the influence of the mechanical activation process on the cordierite-based filler's properties change was examined. First of ...

(International Journal of Cast Metals Research, 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, ...
Comparison of the formation and development of cavitation damage on cast and sintered samples based on basalt
(Journal of Mining and Metallurgy, Section A: Mining, 2019)
The paper examines the resistance to the effect of cavitation of glass-ceramics based on basalt. Two types of samples were investigated: cast and sintered samples based on basalt.The cavitation erosion test was performed ...
Assessment of Grain Size and Grain Refinement Efficiency by Calculation of Released Heat Attributed to Formation of Primary Aluminum Crystals During Solidification of Al7Si4Cu Alloy
(Springer India, New Delhi, )
Assessing heat released only related to the formation of primary crystals provides results with a significantly higher sensitivity than a traditional assessment of undercooling value. In this work, two similar Ti5B1 master ...
