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 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 ...
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 ...
Erosive wear resistance of silicon carbide-cordierite ceramics: influence of the cordierite content
(Inst Za Kovinske Materiale I In Tehnologie, Ljubjana, 2015)
A cordierite/SiC composite was created in situ with reactive sintering at 1250 degrees C and 1300 degrees C. The cordierite precursor was made from commercially available spinel, alumina and quartz and was mixed with the ...
Deformation mechanisms in ti3al-nb alloy at elevated temperatures
(Institute of Metals and Technology, 2010)
Ti3Al-11Nb-1V (x/%) was made in a vacuum arc furnace. Hot-rolling was conducted at 1050 degrees C in a two-phase field of the alloy. Strain-rate jump tests were performed at T = 800-1100 degrees C and strain rates of 10(-6) ...
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 ...
Relationship between the calculated oxygen activity and the sulfur partition ratio for cao-al2o3-sio2-mgo slag during ladle refining
(Institute of Metals and Technology, 2012)
A slag-metal equilibrium study was carried out to investigate the effect of oxygen activity on the sulfur partition for CaO-Al2O3-SiO2-MgO slag. The sulfide capacity C-s prediction models by Sosinsky-Sommerville based on ...
Reduction of ultra-fine tungsten powder with tungsten (vi) oxide in a vertical tube reactor
(Institute of Metals and Technology, 2011)
The reduction of WO(3) with hydrogen in a vertical tube reactor is a new approach to the reduction of tungsten oxide compared to conventional procedures in a stationary layer. The advantage of this method is the intensive ...
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 ...
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 ...
