Biomimetics Design of Tooth Root Zone at Cylindrical Gears Profile
(MDPI AG, Basel, Switzerland, 2023)
During the last few decades, the requirements for modern machine elements in terms of size reduction, increasing the energy efficiency, and a higher load capacity of standard and non-standard gears have been very prevalent ...
Softver u oblasti ispitivanja metalnih materijala / Software in the field of the metal materials testing
(Savez inženjera metalurgije Srbije, Beograd, 2005)
Razvoj softvera u oblasti ispitivanja metala tekao je uporedo sa razvojem računarske opreme - hardvera. Osnovni cilj ovog rada je pokušaj pružanja pregleda postojećeg softvera u oblasti ispitivanja metala. Drugi postavljeni ...
Unapređenje tehnologije aluminotermijskog zavarivanja železničkih šina različitog poprečnog preseka / Improvement of at-welding technology of railway rails with different cross sections
(Savez inženjera i tehničara Srbije, Beograd, 2021)
U radu je prikazana nova tehnologija aluminotermijskog zavarivanja (AT) prelaznih šina 49E1 na 60E1(EN 13674-1:2005.), oslonjena na potpuno nove materijale. Ona se odnosi na pešćane kalupe kod kojih su oblik i dimenzije ...
Synthesizing a new type of mullite lining
(Materials and Technology, 2013)
Various possibilities for developing new mullite-based refractory linings that can be applied in a casting process were investigated and are presented in this paper. An optimization of the refractory-lining composition ...
Comparison of refractory coatings based on talc, cordierite, zircon and mullite for Lost foam casting
(Materials and Technology, 2015)
This study presents the results of an investigation of high-temperature materials refractory coatings based on different refractory fillers including talc, cordierite, zircon and mullite applied in the lost-foam casting ...
Hronologija gubitka integriteta konstrukcija zbog grešaka izrade zavarenih konstrukcija / Chronology of lost structural integrity initiated from manufacturing defects in welded structures
(Institut za ispitivanje materijala, Beograd, 2009)
U različitim vremenskim periodima dolazilo je do gubitka integriteta zavarenih konstrukcija zbog razvoja proizvodnih grešaka zavarenog spoja. Mehanizmi otkaza su bili različiti i uvek su predstavljali novo iskustvo, koje ...
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 ...
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 ...
The Influence of Modifying Methods on the Quality of Eutectic and Hypereutectic Silumine for Diesel Engine Pistons
(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, ...
