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 ...
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 ...
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 ...
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 ...
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 ...
Mechanical and microstructural properties of the fly-ash-based geopolymer paste and mortar
(Institute of Metals and Technology, 2013)
In this paper we have investigated the influence of synthesis parameters on the mechanical properties of the fly-ash-based geopolymer paste and mortars. Moreover, the influence of an addition of limestone sand on the ...
