eng The Quality, Benefits and Differentiation of Aluminium Single Serve Portion Capsules for Drinks
Troskot, Sven; Proso, Andrija; Bošnjak, Ivana; Kužet, Vicko
Acta graphica Vol. 29, No. 4, 2018
Aluminium capsules can be used as the final packaging for any type of powdered foods, such as tea or vitamin and similar hot drinks. Aluminium represents a 100% barrier, is impermeable, extends the shelf life of the final product, is recyclable and an alternative to plastic. A wide range of individualized products, including the capsule as attractive single-use possibility, made it possible to satisfy the preferences and expectations of consumers. Currently two main materials for single serve portion coffee capsules are in use: aluminium and/o...

eng The effects of aluminium on human health
bos Efekti aluminijuma na zdravlje ljudi
Višo, N.; Hrabač, B.
The paper aims at reviewing recent knowledge of the pathophysiological mechanisms involved in aluminium poisoning which is often manifested as anaemia, osteopathy and encephalopathy, In order to clarify the mechanisms of aluminium toxicity its metabolism and ways of human exposure are also described. The immunosuppressive effect as well as certain anticarcinogenic effects of aluminium are still insufficiently well known. It is pointed out that different chemical elements can exert a protective action during aluminium poisoning.

eng Long - range foundry Al composite alloys
Mekhtiev, A. D.; Kosnikov, A. G.; Issin, D. K.; Zholdubaeva, Zh. D.; Issin, B. D.
Metalurgija Vol. 53, No. 4, 2014
The technology of obtaining nanostructural composite aluminum alloys consists in the plasma injection of refractory nanometric particles with simultaneous two-plane magnetic dynamic mixing of the melt. Particularly important in obtaining composite aluminum matrix alloys is the provision of the introduced particles wettability with the matrix melt for forming stable adhesive bonds. Nanostructured powder components can be considered not only to be a starting product for producing nanostructural composite aluminum alloys but as an independent comm...

hrv Primjena aluminijskih konstrukcija u gradnji obiteljskih kuća
eng Use of Aluminium Structures for the Construction of Family Houses
Andrić, Davor; Careva, Kristina; Štulhofer, Ariana
Prostor Vol. 21, No. 1(45), 2013
Članak daje opći i informativni pregled gradnji aluminijskih kuća od prve polovice 20. stoljeća do danas. Aluminij je materijal koji se rijetko koristi za izradu glavne nosive konstrukcije zgrada pa aluminijskih kuća u cijelome svijetu ima malo. Odabrane obiteljske kuće prikazane su kroz njihovu konstrukciju i način gradnje u odnosu s tehnologijom oblikovanja aluminija. Zbog čestih inovacija u gradnji značajan ih je broj sačuvan kao muzejski izlošci.

eng THE AXIAL FORCE IN ALUMINIUM FOAM DRILLING
Ciglar, Damir; Udiljak, Toma; Škorić, Stephan
Tehnički vjesnik Vol. 13, No. 3,4, 2006
Metals in foam shape, the so called metallic foams or metal foams, consist of a base metal material with a certain amount of gas bubbles dispersed throughout the body of the material. These bubbles are actually foam cavities or cells. Metal foams are low-density materials with high strength and rigidity, as well as with good damping capacity. Therefore, their application in the lightweight structure concepts is the object of intensive research. It is possible to join such elements by welding or by screw fastening, and this paper presents the re...

eng Modified low-cycle fatigue (LCF) test
Maj, M.; Klasik, A.; Pietrzak, K.; Rudnik, D.
Metalurgija Vol. 54, No. 1, 2015
The fatigue test results obtained by the common low-cycle fatigue test (LCF) and its modified MLCF counterpart were presented. A satisfactory agreement of results was achieved for the two selected materials. With the MLCF method it is possible to examine from ten to twenty parameters using one single sample only. These parameters characterise the tested material in terms of its mechanical properties under the conditions of mechanical loads. Simultaneously, the study shows the implementation of the modified low-cycle fatigue test in practice.

eng The phenomenon of durability variable dies for aluminum extrusion profiles
Borowski, J.; Wendland, J.
Metalurgija Vol. 55, No. 2, 2016
Extrusion dies are usually regenerated several times (min 4 times). The phenomenon of extended life after each regenerative nitriding process has not been explained. In this work, the regeneration process of dies used in the extrusion of aluminium profiles has been presented. In the article, it was sought to explain the cause of increased die durability after the third or fourth nitriding. Also in this work is presented an analysis of the influence of the parameters of gas nitriding with the ZeroFlow method on hardness of dies. Results were ver...

eng INHIBITION OF ALUMINIUM ALLOY CORROSION IN CHLORIDE SOLUTION BY CAFFEINE ISOLATED FROM BLACK TEA
Gudić, Senka; Zlatunić, Marija; Vrsalović, Ladislav; Radonić, Ani
Hrana u zdravlju i bolesti Vol. 7, No. 1, 2018
Caffeine (1,3,7-trimethylxanthine) was isolated from black tea and characterised using different physical methods. The corrosion inhibition performance of the caffeine isolate (in concentration from 110-5 to 110-3 mol/dm3) on aluminium alloy corrosion in neutral 0.5 mol/dm3 NaCl solution was investigated using potentiodynamic and linear polarization measurements at 20 C. Corrosion potential, corrosion current and polarization resistance were determined and surface coverage of inhibitor molecules and inhibition efficiency were calculated. The...

eng Microstructural and thermal characteristics of the sintered Al-Fe2O3 composites
Boutouta, Aziza; Yacine Debili, Mohamed
Engineering Review Vol. 40, No. 1, 2020
<p>This work has as an objective a study of evolution of characteristic properties of crystalline microstructure and mechanical hardening of aluminum by iron oxide (III), (hematite α-Fe2O3) nan energetic material known as thermite, samples of massive alloys, Al (base)-X wt% Fe2O3 (X =2, 4, 16 and 40) were studied.Al-Fe2O3 composite was developed by a sintering technique from the mixtures of compacted powders of Al high purity and α-Fe2O3 under a temperature of 700 °C for 1 hour and then slowly cooled. We have not noted the formation of thermite...

hrv Korozijske karakteristike sirovog i eloksiranog aluminija
eng Corrosion Characteristics of Raw and Anodised Aluminium
Islamović, S.; Korać, F.; Ostojić, J.; Kezo, M.; Gutić, S.; Koštroman, L.; Halilović, A.
Kemija u industriji Vol. 62, No. 7-8, 2013
Korozijsku postojanost aluminija i njegovih legura u mnogim medijima moguće je povećati različitim postupcima, među kojima se ističu metode anodizacije ili anodne oksidacije, koja se obično naziva eloksiranjem. Korozivna postojanost aluminija nije apsolutna. Aluminij ima slabu otpornost na koroziju u okolišu sa slabom cirkulacijom kisika ili bez nje, obnavljanje pasivnog filma je onemogućeno, materijal više nije korozivno postojan i u tom slučaju odvijaju se korozivni procesi, što se očituje na različite načine. Kao korozivni mediji uzeti...
