Premazi na bazi cirkona sa primenom u Lost Foam procesu livenja / Zircon-based coating for the applications in Lost Foam casting process
(Savez hemijskih inženjera, Beograd, 2012)
U ovom radu je istraživana mogućnost dobijanja novih vatrostalnih premaza na bazi cirkona koji bi imali primenu u livarstvu. Optimizacija sastava premaza kontrolisana reološkim svojstvima postignuta je primenom različitih ...
Failure of steam line causes determined by NDT testing in power and heating plants
(Gruppo Italiano Frattura, 2013)
This paper examines leakage and damages of steam and provides an overview of NDT testing in order to determine the cause of steam lines failure in power plants and heating plants. This approach may be applied to similar ...
Specific features of stainless steel compression elements
(Croatian Soc Civil Engineers-Hsgi, Zagreb, 2015)
Stainless steel has a number of features that define different behaviour of structural elements made of this material, as related to equivalent carbon steel elements. These properties, especially prominent in case of ...
Microstructure and Phase Composition Of Steatite Ceramics Sintered by Traditional and Spark Plasma Sintering
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2018)
The influence of the sintering method on the mineral phase transformations and development of the crystalline microstructure of steatite ceramics was investigated. The steatite samples were fabricated from talc and bentonite ...
Mechanical Activation as Sintering Pre-treatment of Talc for Steatite Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
The effect of vibratory mill induced mechanical activation on the change of the particle size, crystallinity and the phase transformations of the minerals present in the activated material, was studied with the purpose of ...
