Cavitation damages morphology of high-strength low-alloy steel
(Faculty of Metallurgy, 2016)
This paper presents the research into behaviour of HSLA steel affected by cavitation. The parent material (PM) and simulated heat-affected zone (SHAZ) were studied. Ultrasonic vibratory cavitation test was performed in ...
The new tool insert design for prevention the rotation of horizontal wire during shear testing of welded fabric
(Savez inženjera metalurgije Srbije, Beograd, 2019)
Many new requirements in the field of experimental mechanics, like testing of metallic materials, emphasize traceability and accuracy of test results as the end goal. These requirements have energy efficiency context too, ...
Chemometric Analysis of Alternations in Coal Ash Quality Induced by Application of Different Mechano-chemical Processing Parameters
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
The coal fly ash mechano-chemical activation conducted via high energy ultra-centrifugal mill was optimized using mathematical and statistical tools. The aim of the investigation was to accent the merits of alternations ...
Analiza uticaja sučeono zavarenih spojeva na nosivost konstrukcije rezervoara / Analysis of the effects of butt welded joints on a carrying capacity of a structure tank
(Inženjersko društvo za koroziju, Beograd, 2017)
U radu je posle proračuna metodom konačnih elemenata (MKE) analizirana raspodela napona na modelu dela oplate rezervoara pod pritiskom bez zavarenih spojeva (ZS), sa obimnim ZS, podužnim ZS i ukrsnim mestom ZS. Takođe, u ...
Cracking resistance of AlMg4.5Mn alloy TIG welded joints
(Institut za ispitivanje materijala, Beograd, 2011)
In this paper the AlMg4.5Mn TIG welded joints have been tested in order to investigate their cracking resistance. Testing plates, size of 500×250×12 mm, are welded by TIG procedure in a horizontal-vertical position. Various ...
Electro-filter ash use in the underground coal mines
(Institut za rudarstvo i metalurgiju, Bor, 2017)
Thermal power plants in the Republic of Serbia spend 35-40 million tons of coal annually, mostly lignite, with about 6 million tons of ash or slag as a by-product of electricity and heat production, deposited on the ...

Methodological approach of identification and quantification of corrosion damages of the steel tubes which use for casing the well in petroleum industry are presented in the paper. A description and consequence of steel ...
Determination of the apparent porosity level of refractory concrete during a sintering process using an ultrasonic pulse velocity technique and image analysis
(Savez hemijskih inženjera, Beograd, 2010)
Concrete which undergoes a thermal treatment before (pre-casted concrete blocks) and during (concrete embedded in-situ) its life-service can be applied in plants operating at high temperature and as thermal insulation. ...
Makroskopska i mikroskopska identifikacija ostatka na situ 0,063 mm ležišta glina u Srbiji / Macroscopy and microscopy identification of the residue on sieve 0.063 mm of the clay deposits in Serbia
(Institut za rudarstvo i metalurgiju, Bor i Komitet za podzemnu eksploataciju mineralnih sirovina, Resavica, 2007)
Kao sto je poznato, naša zemlja je veoma bogata nalazištima glina. Glina pojedinih ležišta koristi se za proizvodnju keramičkih proizvoda, kvalitetne fasadne opeke, crepa i monte, dok se glina lošijeg kvaliteta, sa ...
Karakterizacija muljeva od neutralizacije otpadnih rastvora i ispirnih voda iz postupka toplog cinkovanja / Characterization of sludge from neutralization of waste solutions and rinsing waters in hot dip galvanizing processes
(Inženjersko društvo za koroziju, Beograd, 2009)
Muljevi nastali rešavanjem otpadnih voda i istrošenih rastvora od pripreme u pogonu toplog cinkovanja spadaju u grupu opasnog industrijskog otpada. Upravljanje ovom vrstom otpada složen je i delikatan posao. Prvi važan ...
