Homogenization of an al-mg alloy and alligatoring failure: alloy ductility and fracture
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2016)
High-strength Al-Mg alloys have a propensity toward hot fracture and failure by alligatoring during hot rolling. In this study the effect of homogenization conditions on the susceptibility of an Al-5.1Mg-0.7Mn alloy toward ...
The nano-wetting aspect at the liquid-metal/sic interface
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2015)
The wetting process on the nano-scale, as an initial and essential step in liquid metal/ceramic joining, is discussed here. Thanks to recent breakthroughs in experimental techniques with nanometre resolution, questions ...
Influence of the matrix type on the temperature responsiveness of a poly-nipaam/chitosan microgel functionalized pes fabric
(Institute of Metals and Technology, 2013)
In this paper, the temperature responsiveness (swelling/de-swelling) of the poly-NiPAAm/chitosan (PNCS) microgel applied to a PBS fabric in combination with two different matrixes, i.e., 1,2,3,4-butanetetracarboxylic acid ...
Wear resistance and dynamic fracture toughness of hypoeutectic high-chromium white cast iron alloyed with niobium and vanadium
(Institute of Metals and Technology, 2014)
The influence of mass fractions 1.5 % Nb and 1.5 % V, added singly and in combination, on the microstructural characteristics and properties relevant to the service performance of the hypoeutectic high-chromium white iron ...
Influence of the thermo-mechanical treatment on the exfoliation and pitting corrosion of an aa5083-type alloy
(Institute of Metals and Technology, 2014)
Exfoliation and pitting corrosion were tested on an AA5083-type alloy sheet, after applying different thermo-mechanical treatments. Hot-rolled plates were laboratory cold rolled with 16-54 % reductions, and subsequently ...
Influence of cold-rolling deformation and annealing temperature on the grain growth of al-4%mg-mn alloy
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2020)
The propensity of an alloy toward an abnormal grain growth (AGG) severely limits the annealing temperature range, capability for hot forming, and deteriorates mechanical properties. In this work, the results of a study of ...
Synthesis of α-Al2O3 based foams with improved properties as catalyst carriers
(Institute of Metals and Technology, 2014)
This paper explores the possibility of synthesising catalyst supports with improved properties. Alumina foams were produced with the polymer replication technique. Representative high- and low-temperature sintering ceramics ...
Multi-criteria analysis of synthesis methods for ni-based catalysts
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2016)
Catalysts based on the Ni/Al2O3 system are used in a variety of catalytic processes. Catalysts are commonly synthesized through thermochemical routes (impregnation, precipitation, coprecipitation and others). The authors ...
Geopolymerization of low-grade bauxite
(Institute of Metals and Technology, 2014)
In terms of quality, bauxite ore can be classified as high- or low-grade ore. High-grade bauxite ores are used for alumina extraction using the Bayer process, while low-grade bauxite ores have a limited application. In ...
Homogenization of an al-mg alloy and alligatoring failure: influence of the microstructure
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2016)
In this study the influence of the microstructure of Al-5.1Mg-0.7Mn alloy on the propensity towards an alligatoring failure was evaluated. The morphology of the constituent particles appears to be the key factor, with ...
