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 ...
Poly(urethane-siloxane)s based on hyperbranched polyester as crosslinking agent: Synthesis and characterization / Poli(uretan-siloksani) na bazi hiperrazgranatog poliestra kao umreživača - sinteza i karakterizacija
(Serbian Chemical Society, 2012)
A series of novel polyurethane crosslinked structures (PUs) was prepared from α,ω-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS-EO), 4,4'-methylenediphenyl diisocyanate and Boltorn ® hyperbranched ...
Supercritical extraction of essential oil from Mentha and mathematical modelling- the influence of plant particle size
(Elsevier Science Bv, Amsterdam, 2012)
Supercritical CO2 extraction was studied using dried leaves of Mentha, originated from the northern part of Libya. Leaves were milled and sieved to obtain different average particles (d(p) = 0.25 - 0.80 mm). They were ...
Whey as a raw material for the production of functional beverages / Surutka kao sirovina za proizvodnju funkcionalnih napitaka
(Association of Chemical Engineers of Serbia, 2012)
One of the least utilized by-products of food industry, despite the great potential that is described, is the whey, which is obtained as a by-product of the technological process production of cheese and casein. The excess ...
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 ...
Impact analysis of airborn pollution due to magnesium slag deposit and climatic changes condition
(Soc Ecological Chemistry & Engineering, Opole, 2012)
The impact of airborne pollution by slag from magnesium production was analyzed under different climate conditions. The slag is characterized by X-ray diffraction analysis, scanning electron microscopy, differential thermal ...
