CORROSION BEHAVIOUR OF AN Al-Zn-Mg-Cu ALLOY AFTER DIFFERENT HEAT TREATMENTS
(Technical faculty Mihajlo Pupin, Zrenjanin, University of Novi Sad, Srbija, 2012)
The variation of factors such as the amount of alloying elements in solid solution, thermal and
thermo-mechanical treatments changes the corrosion tendency in the Al-Zn-Mg-Cu alloy. The measurements of
electrical ...
Corrosion of Archaelogical Artefact made of Forged Iron
(Savez inženjera matalurgije Srbije, Kneza Miloša 9, 11000 Beograd, 2012)
One artefact of the archaeological cultural heritage from Roman period (IV century) that was
found near Šabac in Serbia, was analysed. In corrosion products of the artefact (knife),
dominant phases were goethite (α-FeOOH) ...
Effect of soya milk on antioxidant activity changes in chocolate
(6th Central European Congress on Food, CEFood 2012, 2012)
Properties of chocolate depend on raw chocolate composition, manufacturing process and properly guided phase of precrystallization. In this paper chocolate was produced in a nonconventional way, in the ball mill. Milk ...
Uticaj parametara neselektivne oksidacije na sadržaj funkcionalnih grupa u celuloznim vlaknima / Influence of the nonselective oxidation conditions onto functional groups content in cellulose fibers
(Beograd : Srpsko hemijsko društvo, 2012)
In this paper, the influence of oxidation with hydrogen peroxide onto functional groups content in natural cellulose fibers was studied. Changes in fibers obtained at various modification conditions were evaluated by ...
Influence of TEMPO-Mediated Oxidation on Properties of Hemp Fibers
(Amer Chemical Soc, Washington, 2012)
Hemp fibers are a very interesting natural material for textile and technical applications, but some of these applications require improved and/or specific fiber properties. In order to modify hemp fibers for obtaining ...
A coupled thermo-mechanical model of friction stir welding
(Vinca Institute of Nuclear Sciences, 2012)
A coupled thermo-mechanical model was developed to study the temperature fields, the plunge force and the plastic deformations of Al alloy 2024-T351 under different rotating speed: 350, 400, and 450 rpm, during the friction ...
Friction-stir welding of high-strength aluminium alloys and a numerical simulation of the plunge stage
(Institute of Metals and Technology, 2012)
This paper defines a set of welding parameters for the Friction-Stir Welding (FSW) of two forged panels of the alloy EN AW 7049A in a T652 temper and discusses the plunge stage of FSW using numerical modeling. This ...
