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) ...
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 ...
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 ...
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 ...
Liquid metal/ceramic interfaces in dental practice and jewellery manufacturing
(Institute of Metals and Technology, 2010)
Metal-ceramic fusing has been the essential step in obtaining materials that benefit from both ceramic and metal constituents. i e where the combined properties of metal and ceramic layers are desirable When considering ...
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 ...
Optimization of the recycling processes for magnesium from a highly contaminated waste
(Institute of Metals and Technology, 2014)
With the recently increased use of magnesium alloys, especially in the automotive industry, a large quantity of generated waste, based on magnesium alloys, is expected. Such a waste often contains many impurities such as ...
