-
(Elsevier, 2022-06)Incorporating multicomponent, multiphase, high-temperature, complex chemical equilibrium calculations into process and multiphysics models can provide significant insights into materials, processes and equipment. We refer ...
-
(Elsevier, 2010-09)The conventional casting alloy A356 is probably one of the most popular alloys used for semi-solid metal (SSM) forming. This is due to its high fluidity and good castability. This alloy can be heat treated alternatively ...
-
(Elsevier, 2011-03)The mineral matter in typical feed coals used in South African gasification processes and the ash derived from gasifying such coals have been investigated using a variety of mineralogical, chemical and electron microscope ...
-
(The South African Institute of Mining and Metallurgy, 2008-04)The world mineral industry has over the years experienced growth in the production of nickel (Ni) due to its use not only in the catalytic industry but mainly also its demand in the stainless steel production industry. ...
-
Characteristics of martensite as a function of the Ms temperature in low-carbon armour steel plates (Elsevier, 2009)The microstructure, morphology, crystal structure and surface relief of martensite in a number of experimental armour steel plates with different Ms temperatures were analysed. Atomic force microscopy, thin foil transmission ...
-
(Trans Tech Publications, 2022-03)Oil shales have unstable mechanical and chemical properties, which makes their extraction for characterization and conventional mechanical testing uneasy and complex. Most often, mechanical property measurements are usually ...
-
(Elsevier, 2009-07)Chemical composition and liberation are critical attributes in characterizing a resource stock for beneficiation investigations. Though end-of-life printed circuit board is recognized as a valuable secondary resource stock, ...
-
(Elsevier, 2019-12)Beta (β) solidifying γ-TiAl intermetallic alloys of nominal composition Ti-48Al, Ti-48Al-2Nb, Ti-48Al-2Nb-0.7Cr alloys have been cold pressed and vacuum arc melted. The Al loss was due to compaction method used prior to ...
-
(Springer, 2016-06)Furnace tap-holes vary in design depending on the type of furnace and process involved, but share one common trait: the tap-hole must be opened and closed periodically. In general tap-holes are plugged with refractory clay ...
-
(Springer, 2020-06)The susceptibility to solidification cracking of unstabilized and stabilized ferritic stainless steels was investigated using self-restrained Houldcroft and Modified Varestraint-Transvarestraint (MVT) tests. Nine steel ...
-
(Trans Tech, 2011-06)Semi-solid metal high pressure die casting was used to produce plates from traditional wrought Al-Mg-Si alloys 6082 and 6004, as well as from traditional casting Al-Si-Mg alloys A356 and F357. The high Si-content of the ...
-
(Taylor & Francis, 2015-05)Wear resistance of synthetic graphite against liquid industrial platinum group metals furnace matte (Cu–Fe–Ni–S) was investigated from 800°C to 1450°C at a contact time of 1 hour. Graphite resistance was measured by the ...
-
(Springer, 2015-01)Please read abstract in the article.
-
(Elsevier Science Limited, 2016-12)A major obstacle to the hydrometallurgical treatment of ferromanganese slags is the way in which silica polymerisation is controlled during sulphuric acid digestion and water leaching. In an acidic medium, silica enters ...
-
(Elsevier, 2011-12)The fatigue life of aluminium 6061-T651 at various applied stress amplitudes in the unwelded and welded condition was found to be significantly reduced on immersion in a 3.5% NaCl simulated sea water solution, compared ...
-
(Elsevier, 2008-08)Neither a higher hardness nor higher mechanical properties (yield strength, ultimate tensile strength, impact energy, and %elongation) appear to be exclusive or even reliable criteria for predicting the ballistic performance ...
-
(Elsevier, 2020-06)Impurities present in the sulfate electrolyte during nickel electrodeposition influence the electrowinning process and morphology of deposited nickel metal in various ways. The presence of aluminium can be either detrimental ...
-
Effect of cuprous cyanide, dry and wet milling on the selective flotation of galena and sphalerite (Elsevier, 2006-01)Batch flotation tests of a lead–zinc sulphide composite ore from the Rosh Pinah Mine have been carried out at pH 8.5 in the presence of copper cyanide complexes. These copper cyanide complexes are often found in the recycled ...
-
(Elsevier, 2008)In a hot rolled Nb–Ti and a Nb–Ti–0.09%Mo micro-alloyed steel, the ratio of yield strength to tensile strength (YS/UTS) was found to be a function of the microstructure and cooling rate in those tests where no coiling ...
