(Savez inženjera i tehničara Srbije, 2018)
Aluminijum oksidna (Al2O3) nanovlakna pripremljena su iz vodenog rastvora aluminijum hlorohidrata/poli(vinil alkohola) (PVA) korišćenjem tehnike elektropredenja. Maseni odnos aluminijum hlorohidrata/PVA bio je 5:1. Nakon ...
Salt template zirconia reinforcing particles as possible reinforcement for PMMA matrix composite
(Sage Publications Ltd, London, 2019)
To obtain flakes like zirconia particles at relatively low temperature, the synthesis method for producing zirconia particles on the surface of salt particles that serve as a template is examined. The produced particles ...
A model for cross-referencing and calculating similarity of metal alloys
(Association of Metallurgical Engineers of Serbia, 2013)
This paper presents an innovative model for the comparison and cross- referencing of metal alloys, in order to determine their interchangeability in engineering, manufacturing and material sourcing. The model uses a large ...
The impact of wood fiber surface modification on physical properties of wood-polymer composites / Uticaj modifikacije površine vlakana drveta na mehanička svojstva kompozita polimer-drvo
(Savez inženjera i tehničara Srbije, Beograd, 2016)
In this paper, the impact of wood fiber surface modification on mechanical properties of poly-(methyl methacrylate)(PMMA)-wood composite was examined. FTIR analysis has shown that the wood fiber surface modification was ...
The effect of friction stirs welding speed on microstructure, mechanical properties and IGC of EN AW-5083 plates
(Advanced Technologies and Materials, 2019)
The aim of this work was to evaluate the influence of welding speed on microstructure, mechanical properties, as well as Intergranular corrosion (IGC) susceptibility of EN AW-5083 alloy welded using FSW. FSW was performed ...
